2e8b3425a2 cmd/compile: retire "IsHiddenClosure" and "IsDeadcodeClosure"
Since CL 522318, all closures are now hidden. Thus this CL removes all
codes that worries about hidden vs non-hidden closures.

1c4acea03d internal/trace: make Reader output deterministic
Multiple Ms can offer Events with identical timestamps. The Reader
edits those so the timestamps are strictly increasing, but it needs a
way to break the tie. Use something deterministic (such as the order of
the batches), rather than map iteration order.

Updates #68277

601ea46a53 runtime: add ERMS-based memmove support for modern CPU platforms
The current memmove implementation uses REP MOVSB to copy data larger than
2KB when the useAVXmemmove global variable is false and the CPU supports
the ERMS feature.

This feature is currently only enabled on CPUs in the Sandy Bridge (Client)
, Sandy Bridge (Server), Ivy Bridge (Client), and Ivy Bridge (Server)
microarchitectures.

For modern Intel CPU microarchitectures that support the ERMS feature, such
as Ice Lake (Server), Sapphire Rapids , REP MOVSB achieves better
performance than the AVX-based copy currently implemented in memmove.

20e18c9550 unicode/utf8: AppendRune and EncodeRune performance improvement
- Prefer the evaluation of the valid higher byte-width runes branches
over the one for invalid ones

instead hard code its byte values

Runtime functions, e.g. internal/abi.NoEscape, should not be
instrumented with checkptr. But if they are inlined into a
checkptr-enabled function, they will be instrumented, and may
result in a check failure.

Let the compiler not inline runtime functions into checkptr-
enabled functions.

Also undo the change in the strings package in CL 598295, as the
compiler handles it now.

87abb4afb6 runtime: avoid multiple records with identical stacks from MutexProfile
When using frame pointer unwinding, we defer frame skipping and inline
expansion for call stacks until profile reporting time. We can end up
with records which have different stacks if no frames are skipped, but
identical stacks once skipping is taken into account. Returning multiple
records with the same stack (but different values) has broken programs
which rely on the records already being fully aggregated by call stack
when returned from runtime.MutexProfile. This CL addresses the problem
by handling skipping at recording time. We do full inline expansion to
correctly skip the desired number of frames when recording the call
stack, and then handle the rest of inline expansion when reporting the
profile.

The regression test in this CL is adapted from the reproducer in
https://github.com/grafana/pyroscope-go/issues/103, authored by Tolya
Korniltsev.

Fixes #67548

This reapplies CL 595966.
The original version of this CL introduced a bounds error in
MutexProfile and failed to correctly expand inlined frames from that
call. This CL applies the original CL, fixing the bounds error and
adding a test for the output of MutexProfile to ensure the frames are
expanded properly.

fc51e5023e math/big: fix comment typo in natdiv.go
Comment in line 395:
[x₀ < S, so S - x₀ < 0; drop it]
Should be:
[x₀ < S, so S - x₀ > 0; drop it]

The proof is based on S - x₀ > 0, thus it's a typo of comment.

Fixes #68466

355711821e cmd/internal/cov: close counter data files eagerly
When reading the counter data files from a given pod, close the
underlying *os.File immediately after each one is read, as opposed to
using a deferred close in the loop (which will close them all at the
end of the function). Doing things this way avoids running into "too
many open files" when processing large clumps of counter data files.

Fixes #68468.

8b48290895 cmd/compile: fix recursive generic interface instantiation
When shapifying recursive instantiated types, the compiler ends up
leaving the type as-is if it already has been a shape type. However, if
both of type arguments are interfaces, and one of them is a recursive
one, it ends up being shaped as-is, while the other is shaped to its
underlying, causing mismatch in function signature.

Fixing this by shapifying an interface type as-is, if it is fully
instantiated and already been a shape type.

However, internal/abi is a runtime package, which can not be built with

NoEscape must not be inlined when -d=checkptr is used.
