Also cleanup variable class size calculation for 'new'
statements as well as spread-based indexed field
initialization in Torque rather than in hand-written
ImplementationVisitor code. This is done with new
%-intrinsics. With this change, %-intrinsics can also
have bodies, in which case they are treated as macros.

Roll perfetto to get the fix for a TSAN race.

We need to override a new method on the producer, ClearIncrementalState.
It is only called if the producer opts into it, which we do not so we
add UNREACHABLE() in the implementation.

Now that function counts are based on dedicated call counters instead
of FeedbackVector::invocation_count, we can enable optimizations for
block coverage modes.

This significantly speeds up V8 with enabled coverage:

Before this CL, the web-tooling-benchmark regressed by 70% (block
count coverage vs. no coverage).  With this CL, the regression is
reduced to 40%.

Instead of allocating a fixed array in which we write individually allocate
mutable heap numbers, we can allocate a byte array large enough to cover all
heap numbers. That avoids expensive allocation calls, write barriers, and
temporary memory O(number of heap numbers) (we'll just have 1 byte empty byte
array as overhead).

We already use {base::AddressRegion} in some places, while other places
still receive {Address} and {size_t}. Those are often created from an
existing {base::AddressRegion}, hence pass that on explicitly.

Drive-by: Rename {AssignRanges} to {AssignRange}.
Drive-by^2: Return {base::AddressRegion} by value (it is trivially
            copyable and small).

Perfetto has a mechanism for getting trace data from buffers held alive
by TraceWriters. We enable this with the SetSMBScrapingEnabled() call.

This means we don't need to delete TraceWriter objects and can just leak
them for now, and eventually use thread-local destructors to ensure they
are eventually deleted on thread exit.

Prior to this CL, call counts at function scope were taken from the
FeedbackVector::invocation_count field. This had two major drawbacks:
1. for generator functions, these count the number of resumptions
instead of the number of calls; and 2. the invocation count is not
maintained in optimized code.

The solution implemented here is to add a dedicated call counter at
function scope which is incremented exactly once each time the
function is called.

A minor complication is that our coverage output format expects
function-scope counts in the dedicated CoverageFunction object, and
not as a CoverageBlock. Thus function-scope block counts are initially
marked with magic positions, and later recognized and rewritten during
processing.

This CL thus fixes reported generator function call counts and enables
optimizations in block coverage modes (more to come in a follow-up).

Drive-by: Don't report functions with empty source ranges.

own requested sampling interval, to be snapped to the profiler's
sampling interval. Use the greatest common divisor of all sample rates
to determine what sample rate should be chosen for the sampling thread,
and dispatch samples to attached profilers based on their requested
sample periodicity.
