Without having all the architectures implementing the And/Or operators
merged I can't proceed with the public sync/atomic apis. This CL adds a
generic implementation that should work for all the remaining arches,
while waiting for the native assembly implementations in CL 531835,
CL 531678, CL 531895.
I regret the oversight of not pushing this earlier.

Wasmtime 14.0.0 introduced new CLI flags and removed the existing
flags, in particular the --max-wasm-stack flag we were using to avoid
errors in some tests.
This introduces a regular expression based switch that uses the old
flags for wasmtime versions < 14 and the new flags otherwise.

Currently the final size computed for an object in mallocgc excludes the
allocation header. This is correct in a number of cases, but definitely
wrong for memory profiling because the "free" side accounts for the full
allocation slot.
This change makes an explicit distinction between the parts of mallocgc
that care about the full allocation slot size ("the GC's accounting")
and those that don't (pointer+len should always be valid). It then
applies the appropriate size to the different forms of accounting in
mallocgc.

Add runtime-internal locks to the mutex contention profile.
Store up to one call stack responsible for lock contention on the M,
until it's safe to contribute its value to the mprof table. Try to use
that limited local storage space for a relatively large source of
contention, and attribute any contention in stacks we're not able to
store to a sentinel _LostContendedLock function.
Avoid ballooning lock contention while manipulating the mprof table by
attributing to that sentinel function any lock contention experienced
while reporting lock contention.
Guard collecting real call stacks with GODEBUG=profileruntimelocks=1,
since the available data has mixed semantics; we can easily capture an
M's own wait time, but we'd prefer for the profile entry of each
critical section to describe how long it made the other Ms wait. It's
too late in the Go 1.22 cycle to make the required changes to
futex-based locks. When not enabled, attribute the time to the sentinel
function instead.

A persistent performance regression was discovered on
perf.golang.org/dashboard and this was narrowed down to the switch to
footers. Using allocation headers instead resolves the issue.
The benchmark results for allocation footers weren't realistic, because
they were performed on a machine with enough L3 cache that it completely
hid the additional cache miss introduced by allocation footers.
This means that in some corner cases the Go runtime may no longer
allocate 16-byte aligned memory. Note however that this property was
*mostly* incidental and never guaranteed in any documentation.
Allocation headers were tested widely within Google and no issues were
found, so we're fairly confident that this will not affect very many
users.
Nonetheless, by Hyrum's Law some code might depend on it. A follow-up
change will add a GODEBUG flag that ensures 16 byte alignment at the
potential cost of some additional memory use. Users experiencing both a
performance regression and an alignment issue can also disable the
GOEXPERIMENT at build time.

Previously, we used the presence of individual origin fields
to decide whether an Origin could be checked for staleness,
with a nil Origin representing “use whatever you have”.
However, that turns out to be fairly bug-prone: if we forget
to populate an Origin somewhere, we end up with an incomplete
check instead of a non-reusable origin (see #61415, #61423).
As of CL 543155, the reusability check for a given query
now depends on what is needed by the query more than what
is populated in the origin. With that in place, we can simplify
the handling of the Origin struct by using a nil pointer
to represent inconsistent or unavailable origin data, and
otherwise always reporting whatever origin information we have
regardless of whether we expect it to be reused.

We shouldn't just redact the incomplete information, because it might

reusing it if that information isn't included.

getimpliedreg was used to set a default register in cases where
one was implied but not set by the assembler or compiler.
In most cases with constant values, R0 is implied, and is the value
0 by architectural design. In those cases, R0 is always used, so
treat 0 and REG_R0 as interchangeable in those encodings.
Similarly, the pseudo-register SP or FP is used to in place of the
stack pointer, always R1 on PPC64. Unconditionally set this during
classification of NAME_AUTO and NAME_PARAM as it may be 0.
The case where REGSB might be returned from getimpliedreg is never
used. REGSB is aliased to R2, but in practice it is either R0 or R2
depending on buildmode. See symbolAccess in asm9.go for an example.

Since this doesn't look like a normal closure, ir.Func.OClosure is not

This patch reworks how inlheur.AnalyzeFunc is called by the top level
inliner. Up until this point the strategy was to analyze a function at
the point where CanInline is invoked on it, however it simplifies
things to instead make the call outside of CanInline (for example, so
that directly recursive functions can be analyzed).
Also as part of this patch, change things so that we no longer run
some of the more compile-time intensive analysis on functions that
haven't been marked inlinable (so as to safe compile time), and add a
teardown/cleanup hook in the inlheur package to be invoked by the
inliner when we're done inlining.

TSAN recently got support for Go's new atomic And and Or
operations (#61395). This CL updates the race syso files to
include the change. Also regenerate cgo dynamic imports on darwin.
OpenBSD/AMD64 is not updated, as TSAN no longer supports OpenBSD
(#52090).
Linux/PPC64 is not updated, as I'm running into some builder
issues. Still working on it.
For #61395.
For #62624.

Port CL 408826 and CL 413474 from reflect to internal/reflectlite.
It is a bit simpler as reflectlite has fewer methods.

We no longer force Value content to escape and the compiler's
escape analysis can handle it now.

Before Go 1.21, ValueOf always escapes and a Value's content is
always heap allocated. In Go 1.21, we made it no longer always
escape, guarded by go121noForceValueEscape. This behavior has
been released for some time and there is no issue so far. We can
remove the guard now.
