Although we aren't precise about enforcing the hosts just yet,
we can eventually use the declared hostnames to selectively skip
tests (for example, if an external service has an outage while
a Go release is being tested).
Also relax the constraint to [short] in tests that require only
vcs-test.golang.org, which has redirected to an in-process server
since around CL 427914.
Also enforce that tests that use the network actually use the [net]
constraint, by setting TESTGONETWORK=panic in the test environment
until the condition is evaluated.

The current implementation for this metric populates a histogram
that is never reset, i.e. where each bucket count increases
monotonically.
The comment in the definition of the Cumulative attribute calls
out that cumulative means that if the metric is a distribution,
then each bucket count increases monotonically.
In that sense, the cumulative attribute should be set to true for
this metric.

Currently, a symbol's outer symbol, the "special" attribute, and
whether a symbol is a generator symbol are represented as maps,
and are accessed in some loops over nearly all reachable symbols.
The map lookups are a bit expensive.
For outer symbol, a non-trivial portion of the symbols have outer
symbol set (e.g. type symbols, which we put into container symbols
like "type:*"). Using a slice to access more efficiently.
For the special and generator symbol attributes, use a bitmap.
There are not many symbols have those attributes, so the bitmap is
quite sparse. The bitmap is not too large anyway, so use it for
now. If we want to further reduce memory usage we could consider
some other data structure like a Bloom filter.

This is the AIX and Solaris equivalent of CL 269378.
On AIX and Solaris, where we use libc for syscalls, when the runtime exits,
it calls the libc exit function, which may call back into user code,
such as invoking functions registered with atexit. In particular, it
may call back into Go. But at this point, the Go runtime is
already exiting, so this wouldn't work.
On non-libc platforms we use exit syscall directly, which doesn't
invoke any callbacks. Use _exit on AIX and Solaris to achieve the same
behavior.
Test is TestDestructorCallback.

As part of developing #57411, we ran into cases where a flag was
defined in one package init and Set in another package init, and there
was no init ordering implied by the spec between those two
packages. Changes in initialization ordering as part of #57411 caused
a Set to happen before the definition, which makes the Set silently
fail.
This CL makes the Set fail loudly in that situation.
Currently Set *does* fail kinda quietly in that situation, in that it
returns an error. (It seems that no one checks the error from Set,
at least for string flags.) Ian suggsted that instead we panic at
the definition site if there was previously a Set called on that
(at the time undefined) flag.
So Set on an undefined flag is ok and returns an error (as before),
but defining a flag which has already been Set causes a panic. (The
API for flag definition has no way to return an error, and does
already panic in some situations like a duplicate definition.)

The initial purpose of PCALIGN was to identify code
where it would be beneficial to align code for performance,
but avoid cases where too many NOPs were added. On p10, it
is now necessary to enforce a certain alignment in some
cases, so the behavior of PCALIGN needs to be slightly
different. Code will now be aligned to the value specified
on the PCALIGN instruction regardless of number of NOPs added,
which is more intuitive and consistent with power assembler
alignment directives.
This also adds 64 as a possible alignment value.
The existing values used in PCALIGN were modified according to
the new behavior.
A testcase was updated and performance testing was done to
verify that this does not adversely affect performance.

Add a struct called Source that holds the function, file and line
of a location in the program's source code.
When HandleOptions.AddSource is true, the ReplaceAttr function will
get an Attr whose key is SourceKey and whose value is a *Source.
We use *Source instead of Source to save an allocation. The pointer
and the value each cause one allocation up front: the pointer when it
is created, and the value when it is assigned to the `any` field of a
slog.Value (handle.go:283). If a ReplaceAttr function wanted to modify
a Source value, it would have to create a new slog.Value to return,
causing a second allocation, but the function can modify a *Source in
place.
TextHandler displays a Source as "file:line".
JSONHandler displays a Source as a group of its non-zero fields.
This replaces the previous design, where source location was always a
string with the format "file:line". The new design gives users more
control over how to output and consume source locations.

During bootstrapping, cmd/dist writes a file indicating which
GOOS/GOARCH combinations are valid, and which support cgo-enabled
builds. That information previously went into the go/build package,
but today it fits in more naturally in the internal/platform package
(which already has a number of functions indicating feature support
for GOOS/GOARCH combinations).
Moreover, as of CL 450739 the cmd/go logic for determining whether to
use cgo is somewhat more nuanced than the go/build logic: cmd/go
checks for the presence of a C compiler, whereas go/build does not
(mostly because it determines its configuration at package-init time,
and checking $PATH for a C compiler is somewhat expensive).
To simplify this situation, this change:
- consolidates the “cgo supported” check in internal/platform
(alongside many other platform-support checks) instead of making
it a one-off in go/build,
- and updates a couple of tests to use testenv.HasCGO instead of
build.Default.CgoEnabled to decide whether to test a cgo-specific
behavior.

inverting the relationship between these two constants. While we're
here, we rename StackLimit to StackNosplit to make it clearer what's
being limited.
This change does not affect the values of these constants in the
default configuration. It does slightly change how
StackGuardMultiplier values other than 1 affect the constants, but
this multiplier is a pretty rough heuristic anyway.

We really need 3 mix steps between the data being hashed and the output.
One mix can only spread a 1 bit change to 32 bits. The second mix
can spread to all 128 bits, but the spread is not complete. A third mix
spreads out ~evenly to all 128 bits.
The amd64 version has 3 mix steps.

Currently these fields are uninitialized causing failures on aix-ppc64,
which has a slightly oddly-defined address space compared to the rest.

The gVisor team reported a regression in their checkers,
which don't set Config.GoVersion, processing files that say
//go:build go1.13 but still use 'any' (which happened in Go 1.18).
That situation should continue to work, since it worked before,
so add a special case for not knowing the GoVersion.

Remove calls to Value.Resolve from Record.AddAttrs, Record.Add and Logger.With.
Handlers must resolve values themselves; document that in Handler.
Call Value.Resolve in the built-in handlers.

No actual bugs--other than one panic(nil)--but a
few places where error nilness was unclear.

The point of DialWithTimeout seems to be to test what happens when the
connection times out during handshake. However, the test wasn't
actually verifying that the connection made it into the handshake at
all. That would not only fail to test the intended behavior, but also
leak the Accept goroutine until arbitrarily later, at which point it
may call t.Error after the test t is already done.
Instead, we now:
- retry the test with a longer timeout if we didn't accept a
connection, and
- wait for the Accept goroutine to actually complete when the test
finishes.
Fixes#59646.
