bf5b587089 cmd/dist: convert host tests to use goTest
This adds support for host tests to goTest and registerTest and
modifies all uses of registerHostTest to use goTest and registerTest.

This eliminates the last case where go test command lines are
constructed by hand. Next we'll clean up all of the infrastructure
support for that.

I traced all exec calls from cmd/dist on linux/amd64 and this makes
only no-op changes (such as re-arranging the order of flags).

Preparation for #37486.

898d000c39 cmd/dist: convert most remaining tests to use goTest
This converts most of the remaining manual "go test" command line
construction in cmd/dist to use the goTest abstraction and
registerTest.

At this point, the only remaining place that directly constructs go
test command lines is runHostTest.

This fixes a bug in the "nolibgcc:os/user" test. It was clearly
supposed to pass "-run=^Test[^CS]", but the logic to override the
"-run" flag for "nolibgcc:net" caused "nolibgcc:os/user" to pass
*both* "-run=^Test[^CS]" and "-run=". This was then rewritten into
just "-run=" by flattenCmdline, which caused all os/user tests to run,
and not actually skip the expensive tests as intended. (This is a
great example of why the new abstraction is much more robust than
command line construction.)

I traced all exec calls from cmd/dist on linux/amd64 and, other than
the fix to nolibgcc:os/user, this makes only no-op changes (such as
re-arranging the order of flags).

For #37486.

36ce2ece09 cmd/dist: restructure cgo_test
Currently, dist test has a single test called "cgo_test" that runs a
large number of different "go test"s.

This commit restructures cgo_test into several individual tests, each
of which runs a single "go test" that can be described by a goTest
object and registered with registerTest. Since this lets us raise the
abstraction level of constructing these tests and these tests are
mostly covering the Cartesian product of a small number of orthogonal
dimensions, we pull the common logic for constructing these tests into
a helper function.

For consistency, we now pass -tags=static to the static testtls and
nocgo tests, but this tag doesn't affect the build of these tests at
all. I traced all exec calls from cmd/dist on linux/amd64 and this is
the only non-trivial change.

For #37486.

c3a0854e31 cmd/dist: introduce "go test" abstraction
This introduces an abstraction for constructing and running "go test"
commands. Currently, dist test is basically a shell script written in
Go syntax: it mostly just invokes lots of subprocesses, almost all of
which are "go test" invocations, and it constructs those command lines
directly from strings all over the place.

This CL raises the level of abstraction of invoking go test. The
current level of abstraction is not serving us very well: it's
conveniently terse, but the actual logic for constructing a command
line is typically so spread out that it's difficult to predict what
command will actually run. For example, the `gotest` function
constructs the basic command, but many tests want to override at least
some of these flags, so flattenCmdLine has logic specific to `go test`
for eliminating duplicate flags that `go test` itself would reject. At
the same time, the logic for constructing many common flags is
conditional, leading to a bevy of helpers for constructing flags like
`-short` and `-timeout` and `-run` that are scattered throughout
test.go and very easy to forget to call.

This CL centralizes and flattens all of this knowledge into a new
`goTest` type. This type gives dist a single, unified point where we
can change anything about how it invokes "go test".

There's currently some "unnecessary" abstraction in the implementation
of the goTest type to separate "build" and "run" flags. This will
become important later when we convert host tests and to do separate
build and run steps.

The following CLs will convert dist test to use this type rather than
directly constructing "go test" command lines. Finally, we'll strip
out the scattered helper logic for building command lines.

For #37486.

ad7dc8ad55 math/rand: deprecate Seed
Programs that call Seed and then expect a specific sequence
of results from the global random source (using functions such as Int)
can be broken when a dependency changes how much it consumes
from the global random source. To avoid such breakages, programs
that need a specific result sequence should use NewRand(NewSource(seed))
to obtain a random generator that other packages cannot access.

Fixes #56319.

cd9d26f0da cmd/go: make testterminal18153 a normal test
Currently, cmd/go's testterminal18153 is implemented as a special test
that doesn't run as part of cmd/go's regular tests. Because the test
requires stdout and stderr to be a terminal, it is currently run
directly by "dist test" so it can inherit the terminal of all.bash.

This has a few problems. It's yet another special case in dist test.
dist test also has to be careful to not apply its own buffering to
this test, so it can't run in parallel and it limits dist test's own
scheduler. It doesn't run as part of regular "go test", which means it
usually only gets coverage from running all.bash. And since we have to
skip it if all.bash wasn't run at a terminal, I'm sure it often gets
skipped even when running all.bash.

Fix all of this by rewriting this test to create its own PTY and
re-exec "go test" to check that PTY passes through go test. This makes
the test self-contained, so it can be a regular cmd/go test, we can
drop it from dist test, and it's not sensitive to the environment of
all.bash.

Preparation for #37486.
Updates #18153.

0266671e3d cmd/dist: add curiously missing GOOS/GOARCH combinations
The cmd/dist cgo_test enumerates a large number of platforms in
various special cases. Some combinations are suspiciously absent. This
CL completes the combinations.

I've confirmed using trybots that the newly-enabled tests pass on
android/* (this is not surprising because the gohostos is never
"android" anyway), windows/arm64, linux/ppc64 (no cgo), linux/loong64
(except for one test, filed #56623), linux/mips*, netbsd/arm (except
for one test, filed #56629), and netbsd/arm64. The windows/arm builder
is out to lunch, so I'm assuming that works. Since netbsd/arm and
arm64 mostly passed these tests, I've also enabled them on netbsd/386
and netbsd/amd64, where they seem to work fine as well.

b1678e508b cmd/compile: handle simple inlined calls in staticinit
Global variable initializers like

	var myErr error = &myError{"msg"}

have been converted to statically initialized data
from the earliest days of Go: there is no init-time
execution or allocation for that line of code.

But if the expression is moved into an inlinable function,
the static initialization no longer happens.
That is, this code has always executed and allocated
at init time, even after we added inlining to the compiler,
which should in theory make this code equivalent to
the original:

	func NewError(s string) error { return &myError{s} }
	var myErr2 = NewError("msg")

This CL makes the static initialization rewriter understand
inlined functions consisting of a single return statement,
like in this example, so that myErr2 can be implemented as
statically initialized data too, just like myErr, with no init-time
execution or allocation.

A real example of code that benefits from this rewrite is
all globally declared errors created with errors.New, like

	package io
	var EOF = errors.New("EOF")

Package io no longer has to allocate and initialize EOF each
time a program starts.

Another example of code that benefits is any globally declared
godebug setting (using the API from CL 449504), like

	package http
	var http2server = godebug.New("http2server")

These are no longer allocated and initialized at program startup either.

The list of functions that are inlined into static initializers when
compiling std and cmd (along with how many times each occurs) is:

	cmd/compile/internal/ssa.StringToAux (3)
	cmd/compile/internal/walk.mkmapnames (4)
	errors.New (360)
	go/ast.NewIdent (1)
	go/constant.MakeBool (4)
	go/constant.MakeInt64 (3)
	image.NewUniform (4)
	image/color.ModelFunc (11)
	internal/godebug.New (12)
	vendor/golang.org/x/text/unicode/bidi.newBidiTrie (1)
	vendor/golang.org/x/text/unicode/norm.newNfcTrie (1)
	vendor/golang.org/x/text/unicode/norm.newNfkcTrie (1)

For the cmd/go binary, this CL cuts the number of init-time
allocations from about 1920 to about 1620 (a 15% reduction).

The total executable code footprint of init functions is reduced
by 24kB, from 137kB to 113kB (an 18% reduction).
The overall binary size is reduced by 45kB,
from 15.335MB to 15.290MB (a 0.3% reduction).
(The binary size savings is larger than the executable code savings
because every byte of executable code also requires corresponding
runtime tables for unwinding, source-line mapping, and so on.)

Also merge test/sinit_run.go, which had stopped testing anything
at all as of CL 161337 (Feb 2019) and initempty.go into a new test
noinit.go.

Fixes #30820.

cb5534c1c6 cmd/compile: do not emit a few more basic types from every compilation
We already emit types for any and func(error) string in runtime.a
but unlike the other pre-emitted types, we don't then exclude them
from being emitted in other packages. Fix that.

Also add slices of non-func types that we already emit.

Saves 0.3% of .a files in std cmd deps, computed by adding sizes from:

	ls -l $(go list -export -f '{{.Export}}' -deps std cmd

The effect is small and not worth doing on its own.
The real improvement is making “what to write always in runtime”
and “what not to write in other packages” more obviously aligned.

8477562ce5 cmd/compile: be more careful about pointer incrementing in range loops
For range loops, we use a pointer to the backing store that gets
incremented on each iteration of the loop.

The problem with this scheme is that at the end of the last iteration,
we may briefly have a pointer that points past the end of the backing store
of the slice that is being iterated over. We cannot let the garbage collector
see that pointer.

To fix this problem, have the incremented pointer live briefly as
a uintptr instead of a normal pointer, so it doesn't keep anything
alive. Convert back to a normal pointer just after the loop condition
is checked, but before anything that requires a real pointer representation
(in practice, any call, which is what could cause a GC scan or stack copy).

Fixes #56699
