cf06b1f1db net/url: fix missing handling for opaque value in ResolveReference method
The current implementation doesn't resolve as per spec RFC 3986 the case
where the base URL has an opaque value, and the reference doesn't have
either a scheme, authority or path. Currently, this specific case falls
back to the "abs_path" or "rel_path" cases, where the final path results
of the base_path being resolved relatively to the reference's, but since
the opaque value is stored independently, it needs a case of its own.

The algorith for resolving references is defined in RFC 3986 section 5.2.2:
https://www.rfc-editor.org/rfc/rfc3986.html#section-5.2.2

ca1d2ead5d runtime: skip tracing events that would cause reentrancy
Some of the new experimental events added have a problem in that they
might be emitted during stack growth. This is, to my knowledge, the only
restriction on the tracer, because the tracer otherwise prevents
preemption, avoids allocation, and avoids write barriers. However, the
stack can grow from within the tracer. This leads to
tracing-during-tracing which can result in lost buffers and broken event
streams. (There's a debug mode to get a nice error message, but it's
disabled by default.)

This change resolves the problem by skipping writing out these new
events. This results in the new events sometimes being broken (alloc
without a free, free without an alloc) but for now that's OK. Before the
freeze begins we just want to fix broken tests; tools interpreting these
events will be totally in-house to begin with, and if they have to be a
little bit smarter about missing information, that's OK. In the future
we'll have a more robust fix for this, but it appears that it's going to
require making the tracer fully reentrant. (This is not too hard; either
we force flushing all buffers when going reentrant (which is actually
somewhat subtle with respect to event ordering) or we isolate down just
the actual event writing to be atomic with respect to stack growth. Both
are just bigger changes on shared codepaths that are scary to land this
late in the release cycle.)

Fixes #67379.

ac6dea7aa1 runtime: lower mutex contention test expectations
As of https://go.dev/cl/586796, the runtime/metrics view of internal
mutex contention is sampled at 1 per gTrackingPeriod, rather than either
1 (immediately prior to CL 586796) or the more frequent of
gTrackingPeriod or the mutex profiling rate (Go 1.22). Thus, we no
longer have a real lower bound on the amount of contention that
runtime/metrics will report. Relax the test's expectations again.

efe7a1f5d3 runtime: write out a batch with alignment info for traceallocfree
Currently the traceallocfree experiment is missing info in the trace for
interpeting the produced events. Most notably, the base heap address is
missing. While not technically necessary, it is useful for getting an
accurate picture of the program's memory layout, and will be useful for
future trace experiments. Since we want to emit a batch for this, we
should also emit a batch for all the alignment info that's used to
compress the addresses (IDs) produced for the alloc/free events.

This CL distinguishes the different formats of the experimental batches
(note that there's already batches containing type information in this
experiment) by putting a byte at the beginning of each experimental
batch indicating its format.

This was removed before the latelower pass was introduced to fold

conversion of ANDconst to ANDCCconst into latelower with the other
CC opcodes.

This also requires introducing RLDICLCC to prevent regressions
when ANDconst is converted to RLDICL then to RLDICLCC and back
to ANDCCconst when possible.

44079f39eb cmd/compile: keep closure pointer live for range body closures
For range-over-function, the compiler generates a hidden closure
for the range body, and call the iterator function with the hidden
closure as the yield parameter. For debuggers, if it stops inside
the range body (hidden closure), it needs some way to find the
outer function (that contains the range statement), to access the
variables that are in scope. To do this, we keep the closure
pointer live on stack with a special name ".closureptr", so the
debugger can look for this name and find the closure pointer. In
the usual case, the closure is a struct defined in the outer
frame, so following the pointer it will find the frame. We do this
in SSA generation, so if the range func is inlined and there is no
actual closure, we don't generate any extra code. In the case that
there is an actual closure, it's just a single store to the stack,
so the overhead is still small.

41884dcd05 runtime/pprof: ignore runtime-internal samples in test
Tests of the mutex profile focus on sync.Mutex, which is easy to
control. But since those tests still use the runtime, and contention on
internal runtime.mutex values is now also part of the mutex profile, we
have to filter out those samples before examining the profile. Otherwise
the test may be confused by stray contention on sched.lock (or other
runtime-internal locks) as a natural consequence of using goroutines.

8ab131fb12 runtime: split mutex profile clocks
Mutex contention measurements work with two clocks: nanotime for use in
runtime/metrics, and cputicks for the runtime/pprof profile. They're
subject to different sampling rates: the runtime/metrics view is always
enabled, but the profile is adjustable and is turned off by default.
They have different levels of overhead: it can take as little as one
instruction to read cputicks while nanotime calls are more elaborate
(although some platforms implement cputicks as a nanotime call). The use
of the timestamps is also different: the profile's view needs to attach
the delay in some Ms' lock2 calls to another M's unlock2 call stack, but
the metric's view is only an int64.

Treat them differently. Don't bother threading the nanotime clock
through to the unlock2 call, measure and report it directly within
lock2. Sample nanotime at a constant gTrackingPeriod.

Don't consult any clocks unless the mutex is actually contended.

Continue liberal use of cputicks for now.

3128ebfad7 crypto/tls: clarify group selection logic
I initially thought the logic was broken, but writing the test I
realized it was actually very clever (derogative). It was relying on the
outer loop continuing after a supported match without a key share,
allowing a later key share to override it (but not a later supported
match because of the "if selectedGroup != 0 { continue }").

Replaced the clever loop with two hopefully more understandable loops,
and added a test (which was already passing).

We were however not checking that the selected group is in the supported
list if we found it in key shares first. (This was only a MAY.) Fixed.
