4ad4128d3c cmd/compile: fix bad order of evaluation for min/max builtin
For float or string, min/max builtin performs a runtime call, so we need
to save its result to temporary variable. Otherwise, the runtime call
will clobber closure's arguments currently on the stack when passing
min/max as argument to closures.

Fixes #60990

4f36f7e4dd encoding: document that base32 and base64 do not use UTF-8
The invention of base32 and base64 predates the invention of UTF-8
and was never meant to output valid UTF-8.
By default, the output is always valid ASCII (and thus valid UTF-8)
except when the user specifies an alphabet or padding value
that is larger than '\x7f'. If that is done,
then the exact byte symbol is used rather than the UTF-8 encoding.

Fixes #60689

13529cc5f4 syscall: try non-blocking stdio on wasip1
Try to set stdio to non-blocking mode before the os package
calls NewFile for each fd. NewFile queries the non-blocking flag
but doesn't change it, even if the runtime supports non-blocking
stdio. Since WebAssembly modules are single-threaded, blocking
system calls temporarily halt execution of the module. If the
runtime supports non-blocking stdio, the Go runtime is able to
use the WASI net poller to poll for read/write readiness and is
able to schedule goroutines while waiting.

d49017a7c3 go/types, types2: fix interface unification
When unification of two types succeeds and at least one of them
is an interface, we must be more cautious about when to accept
the unification, to avoid order dependencies and unexpected
inference results.

The changes are localized and only affect matching against
interfaces; they further restrict what are valid unifications
(rather than allowing more code to pass). We may be able to
remove some of the restriotions in a future release.

See comments in code for a detailed description of the changes.

Also, factored out "asInterface" functionality into a function
to avoid needless repetition in the code.

Fixes #60933.
Fixes #60946.

a031f4ef83 cmd/compile: fix min/max builtin code generation
Our large-function phi placement algorithm is incompatible with phi
opcodes already existing in the SSA representation. Instead, use simple
variable assignments and have the phi placement algorithm place the phis
we need for min/max.

Turns out the small-function phi placement algorithm doesn't have this
sensitivity, so this bug only occurs in large functions (>500 basic blocks).

Maybe we should document/check that no phis are present when we start
phi placement (regardless of size).  Leaving for a potential separate CL.

We should probably also fix the placement algorithm to handle existing
phis correctly.  But this CL is probably a lot smaller/safer than
messing with phi placement.

48dbb6227a runtime: set raceignore to zero when starting a new goroutine
When reusing a g struct the runtime did not reset
g.raceignore. Initialize raceignore to zero when initially
setting racectx.

A goroutine can end with a non-zero raceignore if it exits
after calling runtime.RaceDisable without a matching
runtime.RaceEnable. If that goroutine's g is later reused
the race detector is in a weird state: the underlying
g.racectx is active, yet g.raceignore is non-zero, and
raceacquire/racerelease which check g.raceignore become
no-ops. This causes the race detector to report races when
there are none.

which ends up making the wrapper function now inlineable, but can

contain OMETHVALUE nodes that we never seen, thus we need to scan

36edde9d9f cmd/go: shorten longest 5 tests
Running go test -parallel=1 -v, these are the top 10 tests:

PASS: TestScript/mod_invalid_version 40.14s
PASS: TestScript/build_cache_output 46.82s
PASS: TestScript/get_legacy 48.69s
PASS: TestTestCache 58.44s
PASS: TestScript/mod_get_direct 62.88s

PASS: TestScript/gcflags_patterns 95.17s
PASS: TestScript/mod_list_compiled_concurrent 124.31s
PASS: TestScript/vet_flags 202.85s

Change the top 5 not to run builds at all, so they don't
have to use -a or clear the go build cache.

mod_get_direct should be replaced with a vcs-test test.
mod_invalid_version should be replaced with a vcs-test test.
get_legacy should be deleted eventually.

a7b1793701 cmd/go: do not index std as a module in modcache
We do not index std as a whole module ever.

When working in the main Go repo, files in package change often,
so we don't want to pay the cost of reindexing all of std when what
we really need is just to reindex strings. Per-package indexing
works better for that case.

When using a released Go toolchain, we don't have to worry about
the whole module changing, but if we switch to whole-module indexing
at that point, we have the potential for bugs that only happen in
released toolchains. Probably not worth the risk.

For similar reasons, we don't index the current work module as
a whole module (individual packages are changing), so we use the heuristic
that we only do whole-module indexing in the module cache.

The new toolchain modules live in the module cache, though, and
our heuristic was causing whole-module indexing for them.
As predicted, enabling whole-module indexing for std when it's
completely untested does in fact lead to bugs (a very minor one).

This CL turns off whole-module indexing for std even when it is
in the module cache, to bring toolchain module behavior back in
line with the other ways to run toolchains.

For #57001.

GOROOT/test is pruned out by cmd/distpack. It isn't really needed for
the test anyway; the test can instead use the "src/unicode" subdirectory,
which is even within the same module.

This test was previously adjusted in CL 13467045 and CL 31859.

Unlike in previous iterations of the test, the directories used in
this revision are covered by the Go 1 compatibility policy and thus
unlikely to disappear.
