TypeFeedbackVectors are strongly rooted by a closure. However, in modern
JavaScript closures are created and abandoned more freely. An important
closure may not be present in the root-set at time of garbage collection,
even though we've cached optimized code and use it regularly. For
example, consider leaf functions in an event dispatching system. They may
well be "hot," but tragically non-present when we collect the heap.
Until now, we've relied on a weak root to cache the feedback vector in
this case. Since there is no way to signal intent or relative importance,
this weak root is as susceptible to clearing as any other weak root at
garbage collection time.
Meanwhile, the feedback vector has become more important. All of our
ICs store their data there. Literal and regex boilerplates are stored there.
If we lose the vector, then we not only lose optimized code built from
it, we also lose the very feedback which allowed us to create that optimized
code. Therefore it's vital to express that dependency through the root
set.
This CL does this by creating a strong link to a feedback
vector at the instantiation site of the function closure.
This instantiation site is in the code and feedback vector
of the outer closure.

With the old logic, a suppression shows up in the statistics independent if the test cases caused a difference or not. This doesn't give a signal if a suppression is useful. The new logic will help cleaning up suppressions that never apply.

This adds optional multi-architecture builds, allowing to compile
x86 and x64 in one build. The correctness fuzzer can be configured to
compare the two executables, e.g. to compare x86 to x64 run the
launcher with: --second-d8=clang_x86/d8 in an x64 build.
Configuring the executable's architecture is now simplified and
inferred from the gn build configuration.
Building for clusterfuzz has now a new canonical target that can be
used by the infrastructure (defaults to d8).
The clusterfuzz release builder is now defined to compile
multi-arch builds, which will have an effect as soon as the
infrastructure refers to the new clusterfuzz target.

Previously (and still currently for some of them), post-mortem debugging
tools were using StandardFrameConstants::kContextOffset as the offset to
get the value that represents a frame's type.
However since https://codereview.chromium.org/1696043002, a new, more
general offset was introduced:
CommonFrameConstants::kContextOrFrameTypeOffset.
In order for post-mortem debugging tools to use this constant, it is
included in the generated post-mortem metadata.

This disables optimizations when using typed float arrays in
correctness fuzzer test cases. Otherwise, different NaN patterns
in float typed arrays might lead to different observations when
