The use of an empty import "C" to trigger cgo in runtime/race
serves two purposes:
1. Cause the runtime to use the C library to create system threads,
because the race syso implementation expects things like
thread-local storage to work correctly.
2. Derive the right set of //go:cgo_import_dynamic comments
to pass to the Go linker, so that it doesn't diagnose them as
undefined references.
On macOS, (1) is unnecessary because using the C library
(via DLL calls) is the only way the runtime ever creates threads.
We can accomplish (2) by writing those comments ourselves.
Having done that in this CL, cgo is no longer needed to run
the race detector on macOS, which means that having a
pre-compiled set of .a files is no longer necessary,
nor is having Xcode for use with cgo when rebuilding those .a files.

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.)

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.

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.

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.

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.

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).
