CL 310850 dropped work re-checks on non-spinning Ms to fix#43997.
This introduced a new race condition: a non-spinning M may drop its P
and then park at the same time a spinning M attempts to wake a P to
handle some new work. The spinning M fails to find an idle P (because
the non-spinning M hasn't quite made its P idle yet), and does nothing
assuming that the system is fully loaded. This results in loss of work
conservation. In the worst case we could have a complete deadlock if
injectglist fails to wake anything just as all Ps are going idle.
sched.needspinning adds new synchronization to cover this case. If work
submission fails to find a P, it sets needspinning to indicate that a
spinning M is required. When non-spinning Ms prepare to drop their P,
they check needspinning and abort going idle to become a spinning M
instead. This addresses the race without extra spurious wakeups. In the
normal (non-racing case), an M will become spinning via the normal path
and clear the flag.
injectglist must change in addition to wakep because it is a similar
form of work submission, notably used following netpoll at a point when
we might not have a P that would guarantee the work runs.

Currently, trace.lock can be acquired while on a user G and stack
splits can happen while holding trace.lock. That means every lock used
by the stack allocator must be okay to acquire while holding
trace.lock, including various locks related to span allocation. In
turn, we cannot safely emit trace events while holding any
allocation-related locks because this would cause a cycle in the lock
rank graph.
To fix this, require that trace.lock only be acquired on the system
stack, like mheap.lock. This pushes it into the "bottom half" and
eliminates the lock rank relationship between tracing and stack
allocation, making it safe to emit trace events in many more places.
One subtlety is that the trace code has race annotations and uses
maps, which have race annotations. By default, we can't have race
annotations on the system stack, so we borrow the user race context
for these situations.
We'll update the lock graph itself in the next CL.
For #53979. This CL technically fixes the problem, but the lock rank
checker doesn't know that yet.

Currently, the stack frame of (*traceStackTable).dump is 68KiB. We're
about to move (*traceStackTable).dump to the system stack, where we
often don't have this much room.
5140 bytes of this is an on-stack temporary buffer for constructing
potentially large trace events before copying these out to the actual
trace buffer.
Reduce the stack frame size by writing these events directly to the
trace buffer rather than temporary space. This introduces a couple
complications:
- The trace event starts with a varint encoding the event payload's
length in bytes. These events are large and somewhat complicated, so
it's hard to know the size ahead of time. That's not a problem with
the temporary buffer because we can just construct the event and see
how long it is. In order to support writing directly to the trace
buffer, we reserve enough bytes for a maximum size varint and add
support for populating a reserved space after the fact.
- Emitting a stack event calls traceFrameForPC, which can itself emit
string events. If these were emitted in the middle of the stack
event, it would corrupt the stream. We already allocate a []Frame to
convert the PC slice to frames, and then convert each Frame into a
traceFrame with trace string IDs, so we address this by combining
these two steps into one so that all trace string events are emitted
before we start constructing the stack event.

In go.dev/cl/413396, I implemented implicit conversions by setting the
conversion's position to the enclosing statement that necessitated the
conversion. However, users actually want the position information to
be at the expression itself, and this seems sensible anyway.
This was noticed because x/tools had a test for:
fmt.Println(42)
and it was checking where the escape analysis diagnostic for
`42` (really `any(42)`) was reported.
Historically, we reported the column of the `4`; but CL 413396 caused
unified IR to instead report the column of the `(` instead (the
position associated with the call expression, which forced `42` to be
implicitly converted from `int` to `any`).
I chalk this mistake up to being accustomed to working with ir, where
we can't reliably use n.Pos() because of how ONAME positions work, so
I was trying to avoid relying on the implicitly converted expression's
own position.

The current implementation of compilerVersion incorrectly gives an
error message that the compiler version is too old even though the
system has a recent compiler. This happens for specifically for the
gcc compiler and causes ASAN tests to be skipped.
Replacing -v with gcc dump version options seems to fix it. Running
./testsanitizers.test -test.v now shows the ASAN tests being run.

The comment claims that reflect users cannot obtain an unsafe.Pointer
without also importing the unsafe package explicitly.
This is no longer true now that the Value.UnsafePointer method
directly returns an unsafe.Pointer.
