9a5574afe6 go/printer: reduce allocations to improve performance
First, we know that Go source files almost always weigh at least a few
kilobytes, so we can kickstart the output buffer to be a reasonable size
and reduce the initial number of incremental allocations and copies when
appending bytes or strings to output.

Second, in nodeSize we use a nested printer, but we don't actually need
its printed bytes - we only need to know how many bytes it prints.
For that reason, use a throwaway buffer: the part of our output buffer
between length and capacity, as we haven't used it yet.

Third, use a sync.Pool to reuse allocated printers.
The current API doesn't allow reusing printers,
and some programs like gofmt will print many files in sequence.

Those changes combined result in a modest reduction in allocations and
CPU usage. The benchmark uses testdata/parser.go, which has just over
two thousand lines of code, which is pretty standard size-wise.

We also split the Print benchmark to cover both a medium-sized ast.File
as well as a pretty small ast.Decl node. The latter is a somewhat common
scenario in gopls, which has code actions which alter small bits of the
AST and print them back out to rewrite only a few lines in a file.

41089704dd all: transfer reflect.{SliceHeader, StringHeader} to unsafeheader.{Slice, String}
After we deprecated reflect.{SliceHeader, StringHeader}, it is recommended
to use unsafe.{Slice, String} to replace its work. However, the compiler
and linker cannot be migrated for the time being.

As a temporary strategy, using the "internal/unsafeheader" package like
other code is the most suitable choice at present.

For #53003.

d734203e39 reflect: deprecate SliceHeader and StringHeader
As discussed in CL 401434 there are substantial misuses of these in the
wild, and they are a potential source of unsafety even for code that
does not use them directly.

Since proposal #53003 has already been implemented, now is the right
time to deprecate reflect.{SliceHeader, StringHeader}.

For #53003.

3585e9be67 os: fix wrong error msg from TestDoubleCloseError
When the type assertion fails, the test mistakenly prints the expected
(rather than the actual) type.

When the error string doesn't match, the text mistakenly prints the
original (rather than the converted) error (although there might not be
any difference in the output, the code looks wrong).

Fix both issues.

e20106ac00 time: optimize FixedZone by caching unnamed zones by the hour
FixedZone is transitively called by Time.UnmarshalJSON or Time.UnmarshalText
for any RFC 3339 timestamp that is not in UTC.
This function is relatively slow since it allocates 3 times.

Given that RFC 3339 never has a zone name and most offsets are by the hour,
we can cache unnamed zones on hour offsets.
Caching a Location should be safe since it has no exported fields or methods
that can mutate the Location. It is functionally immutable.

The only way to observe that the Location was cached is either
by pointer comparison or by shallow copying the struct value.
Neither operation seems sensible to do with a *time.Location.

Performance:

	name           old time/op  new time/op  delta
	UnmarshalText  268ns ± 2%   182ns ± 1%  -32.01%  (p=0.000 n=10+10)

5a37965495 runtime: make mheap.pagesInUse an atomic.Uintptr
This change fixes an old TODO that made it a uint64 because it would
make alignment within mheap more complicated. Now that we don't have to
worry about it since we're using atomic types as much as possible,
switch to using a Uintptr. This likely will improve performance a tiny
bit on 32-bit platforms, but really it's mostly cleanup.

a50c434308 cmd/asm: improve argument to obj.Prog assignment on PPC64
These can be simplified with the knowledge of how arguments are
assigned to obj.Prog objects on PPC64. If the argument is not
a register type, the Reg argument (a2 in optab) of obj.Prog is
not used, and those arguments are placed into RestArgs (a3, a4, a5
in optab).

This relaxes the special case handling enforced by IsPPC64RLD and
IsPPC64ISEL. Instead, arguments are assigned as noted above, and
incorrect usage of such opcodes is checked by optab rules, not by
the assembler front-end.

Likewise, add support for handling 6 argument opcodes, these do
not exist today, but will be added with ISA 3.1 (Power10).

Finally, to maintain backwards compatibility, some 4-arg opcodes
whose middle arguments are a register and immediate, could swap
these arguments and generate identical machine code. This likely
wasn't intended, but is possible. These are explicitly fixed up
in the backend, and the asm tests are extended to check these.

e828fbdffe os/exec: skip TestFindExecutableVsNoexec if mount failed
Apparently, some testing environments do not allow root to mount tmpfs
(due to e.g. AppArmor profile disallowing mount(2) syscall).

Always skip the test if the mount has failed.

Fixes the test issue introduced by CL 414824.

dfdf55158d cmd/compile/internal/noder: fix type switch case vars package
When naming case variables, the unified frontend was using
typecheck.Lookup, which uses the current package, rather than
localIdent, which uses the package the variable was originally
declared in. When inlining across package boundaries, this could cause
the case variables to be associated with the wrong package.

In practice, I don't believe this has any negative consequences, but
it's inconsistent and triggered an ICE in typecheck.ClosureType, which
expected all captured variables to be declared in the same package.

Easy fix is to ensure case variables are declared in the correct
package by using localIdent.

Fixes #54912.
