The check finds implicit conversions of integer literals to bools:
 bool b1 = 1;
 bool b2 = static_cast<bool>(1);
and transforms them to:
 bool b1 = true;
 bool b2 = true;

This is a reland of 91f08378

When the class scope does not need a context, the deserialized
outer scope of the initializer scope would not be the class scope,
and we should not and do not need to use it to fix up the allocation
information of the context-allocated variables. The original patch
did not consider this case and resulted in a regression when we
tried to reparse the initializer function to look for destructuring
assignment errors. This fixes the regression by not deserializing
the class scope that's going to be reparsed, and using the positions
of the scopes to tell whether the scope info matches the reparsed
scope and can be used to fix up the allocation info.

Original change's description:
> [class] implement reparsing of class instance member initializers
>
> Previously, since the source code for the synthetic class instance
> member initializer function was recorded as the span from the first
> initializer to the last initializer, there was no way to reparse the
> class and recompile the initializer function. It was working for
> most use cases because the code for the initializer function was
> generated eagarly and it was usually alive as long as the class was
> alive, so the initializer wouldn't normally be lazily parsed. This
> didn't work, however, when the class was snapshotted with
> v8::SnapshotCreator::FunctionCodeHandling::kClear,
> becuase then we needed to recompile the initializer when the class
> was instantiated. This patch implements the reparsing so that
> these classes can work with FunctionCodeHandling::kClear.
>
> This patch refactors ParserBase::ParseClassLiteral() so that we can
> reuse it for both parsing the class body normally and reparsing it
> to collect initializers. When reparsing the synthetic initializer
> function, we rewind the scanner to the beginning of the class, and
> parse the class body to collect the initializers. During the
> reparsing, field initializers are parsed with the full parser while
> methods of the class are pre-parsed.
>
> A few notable changes:
>
> - Extended the source range of the initializer function to cover the
>   entire class so that we can rewind the scanner to parse the class
>   body to collect initializers (previously, it starts from the first
>   field initializer and ends at the last initializer). This resulted
>   some expectation changes in the debugger tests, though the
>   initializers remain debuggable.
> - A temporary ClassScope is created during reparsing. After the class
>   is reparsed, we use the information from the ScopeInfo to update
>   the allocated indices of the variables in the ClassScope.

The allocatable registers have holes, so not all FP registers are one
half of a valid SIMD register. Thus check if {GetAliases} returned an
allocatable SIMD register before looking up if that register is being
used. Otherwise we run into a DCHECK because {simd_reg} is invalid.

The bug was only introduced recently: https://crrev.com/c/3404780

This turns some CHECKs in the mid-tier register allocator into DCHECKs.
The ones inside {CheckConsistency} should be DCHECKs anyway, even if
they are inside an "#ifdef DEBUG" block. This will make ClusterFuzz
correctly detect them as "checks that only happen in debug mode".
Others were just unnecessarily always included, instead of only in debug
builds.

The C-API does not support dynamic tiering and still waits for top-tier
compilation to finish before serializing code when the explicit
serialize() function gets called. This means that serialize() can only
finish if the kFinishedTopTierCompilation event was triggered first.
With this CL the kFinishedTopTierCompilation event is also triggered
after deserialization so that serialize() can work after
deserialization.

We used to serialize the full source code of the script being
serialized. This CL makes the source code maximally minimal (only
including the needed outer functions) while maintaining the "inner
function is textually inside its outer function" relationship.

Allow Wasm to generate calls directly to Fast API C functions.
This massively reduces the overhead of these calls (~300%).
Currently options parameter is not supported.

This is a reland of
https://chromium-review.googlesource.com/c/v8/v8/+/3364356
with a fix to a data race.
