Feedback from Microsoft partners indicates that it would be beneficial
to enable ETW stack-walking events by default.

This is difficult, because the --interpreted-frames-native-stack flag
comes with a significant perf degradation. Ideally, we would turn
this flag on dynamically, only when a ETW recorder is actively
triggering the provider. Unfortunately, the flag in its current state
cannot be enabled dynamically.

In light of this, we have decided to only flip the build flag.

We are overwriting rhs when dst == rhs && dst != lhs. This is not a
problem on TurboFan because we specify unique registers and dst == lhs
in the instruction-selector.

The fix is to use the helper EmitSimdCommutativeBinOp, which will check
for dst == rhs (pmuludq is commutative).

It's locked exclusively in the MapUpdater API methods, and locked
shared in ComputePropertyAccessInfo (CPAI).

This lock is a step towards running CPAI on background threads. The
simple lock portion is landed separately in this CL to get an early
signal on potential lock overhead perf impact.

The lock is implemented and used very conservatively at the moment:

- it's a single global lock (and not e.g. per-map).
- it's locked for the entire method call duration (instead of only in
  relevant parts).

Both points can potentially be improved in the future.

This fixes a bug introduced in crrev.com/c/2660995.
String.prototype.indexOf must clamp the `position` argument as per
step:

  7. Let start be the result of clamping pos between 0 and len.

Source: tc39.es/ecma262/#sec-string.prototype.indexof

Previously, this was done in the StringIndexOf builtin, but the recent
refactor changed builtin implementations to match the spec more
closely (i.e. to clamp in String.prototype.indexOf, not
StringIndexOf). This means we now have to clamp in
JSCallReducer::ReduceStringPrototypeIndexOf.

Main change: Remove CALL_INTERFACE macro. Use
CALL_INTERFACE_IF_REACHABLE or invoke interface directly instead.
Reasoning: Interfaces assume the Decoder is in a non-error state,
therefore CALL_INTERFACE invoked DCHECK(this->ok()). However,
CALL_INTERFACE (1) was sometimes erroneously called with an error in the
decoder, especially in cases where the error occurred inside immediate
argument parsing, (2) was always called in contexts where the current
control was guaranteed to be reachable. Due to (1) and (2),
CALL_INTERFACE is equivalent to CALL_INTERFACE_IF_REACHABLE (there are
a few exceptions where we can call the interface directly).

Additional change:
- Rename current_code_reachable_ to current_code_reachable_and_ok_
  to make its name reflect its meaning better.

Assembler::EmitVeneers has potential quadratic behavior, which appears
as hangs on chromecrash (see the linked bug). We iterate a list of
branches (unresolved_branches_), and for each branch iterate yet another
list of branches (the label link list in
RemoveBranchFromLabelLinkChain).

Ordering decisions increase the problem, by iterating in the outer loop
in ascending pc offset order, and in the inner loop (which removes the
branch from the linked list) in descending order.

This CL mostly refactors the outer loop:

- Instead of iterating over the whole unresolved_branches_ list, iterate
only the relevant part.
- Call RemoveBranchFromLabelLinkChain in descending pc offset order.
- Keep veneer emission in ascending pc offset order.

Move the helper class and some function definitions into
SharedTurboAssembler. We leave most of the other function definitions
inside of macro-assembler-x64, and will move them later.

Also move i16x8.ext_mul high as a check that this code movement works.

The trace_event_common.h header file isn't used with Perfetto any
longer, so avoid adding a dependency to it from cppgc. Additionally
v8_tracing should be a public dependency so that any public headers
exposed from the target can also include tracing-related headers.
