Previously, when the Load IC saw a deprecated map, it would migrate to
the new map but not update the feedback vector. This would lead to a
deopt the next time the same object was seen.

With this CL, the feedback vector will be updated to the target of the
deprecated map. In order to do this, we need to mark the IC for
recomputation. Without that call, the map and handler would look the
same to IC::UpdatePolymorphicIC amd would decline to update, causing
the IC to go megamorphic instead.

The V8.Execute histogram is not free and can cause more overhead
than expected. This CL is guarding slower histograms behind a new
--slow-histograms flag.

For now --slow-histograms is enabled by default. Once all
chrome-side changes and benchmark changes have landed it will be
disabled by default.

--dump-counters will automatically enable --slow-histograms.

The goal is to not report slow histograms on UMA by default on stable:
- 100% reporting on canary/dev/beta
- 1% reporting on stable or specific finch experiments

Since recently, the WebAssembly instance gets cached in Liftoff code
to avoid reloading it from the stack whenever it is used. Typically the
cached instance gets invalidated at a function call and therefore does
not need to be recorded in safepoints.

However, when the DebugBreak builtin is called, the cached instance
was not invalidated. It is even incorrect to invalidate the cached
instance there because that would modify the CacheState of Liftoff.
Therefore this CL adds the register that caches the instance to the
safepoint of the call to the DebugBreak builtin.

Replace the hard-coded blocklist ("Response.body" and "Request.body") in
the V8 inspector with proper side-effect free debug evaluate. This is
otherwise a non-functional change and in particular preserves the
behavior of reporting accessors as (own) data properties. That will be
tackled in a follow-up CL.

This CL is possible because with https://crrev.com/c/3056879 Blink now
properly marks accessors as side-effect free consistently with what the
V8 inspector had done before.

The original CL was flaky because deserialization did not wait correctly
for the compilation of missing functions to finish. The baseline-finished
event was set even when there were still some functions missing. The
combination of deserialization and lazy compilation was also not handled
correctly.

pthread_rwlock_t can deadlock on Mac if signals are sent to the process
in the wrong moment. Since we use processes e.g. for sampling profiling
(in both d8 and in Chrome), we hence cannot safely use pthread_rwlock_t
on Mac. Instead, fall back to a non-shared pthread_mutex_t.

Interestingly, this shows no measurable performance impact in Wasm
