v8_debug_helper attempts to flag known object pointers when it can
recognize them, even if the memory pointed to is not available in the
crash dump. In ptr-compr builds, the first pages of the map space,
read-only space, and old space are always at the same offsets within the
heap reservation region, so we can more easily detect known objects.

This CL implements the tier-up strategy where the interpreter can be used for
an arbitrary number of executions for every regex, before tiering-up to the
compiler. The only exception is for functional global replaces, where we
eagerly tier-up to native code right away.
To use the tier-up logic --regexp-tier-up=value needs to be set. It is
currently set to 0 by default.

The fuzzer found a crash when we want to execute the {valueOf} function
of an imported value for an i64-global. The problem is that we cannot
execute JavaScript at that moment (I did not check why, I guess we open
some scope at some point). I checked the WebAssembly spec now, and it
defines that only numbers are valid values for imported globals. I
adjust our bigint implementation accordingly with this CL, i.e. that
only bigint values are valid as imported i64-globalsl.
I also created github issues to discuss this problem.

It is not recommended to define type alias in C++ header file. cctest defines
type alias `using Label=CodeAssemblerLabel` in anonymous namespace under
namespace `v8::internal::compiler` in test-code-assembler.cc. This is fine
because this type alias is expected to take effect only in this .cc file. But in
jumbo build, multiple source files are combined as a single one, and the
previous `Label` type alias could shadow definition of `Label` from other header
file (for example, v8/src/codegen/label.h which is included by another .cc file)
This is totally unexpected and triggers bad class layout and accessing in the
latter .cc file for the places where `Label` is referenced.
This change fixes cctest from Windows ARM64 jumbo build, but it applies to
other architectures too.

Async functions were not correctly fixed up for code coverage, which
caused an additional uncovered range to be reported between a return
statement and the closing bracket.
This CL adds code that detects such ranges, and removes them, similarly
to how the ranges are removed for normal functions. The removal process
is different, because the parser rewrites async functions to contain a
try-catch handling promise rejection.

Implement I64x2 multiply using 32-bit multiplies.
This approach uses two fewer cycles (0.88x) on Cortex-A53 and three fewer cycles (0.86x)
on Cortex-A72, compared to moving to general purpose registers and doing two 64-bit multiplies.
Based on a patch by Zhi An Ng.

I don't know if there is another problem, but this change fixes all
problems in the test case. The fuzzer will eventually tell us if there
is another problem.

Reason for revert: This CL is not what I wanted to land. I mixed up my local branches.

This is a reland of ab089c7864, after
making a flaky test more robust.

Use the position of commas in async arrow expressions to mark the
initializer position of any parameters that might have been set in the
preceding parameter.
This extends https://chromium-review.googlesource.com/c/v8/v8/+/1710671
to async arrow heads.

Original change's description:
> Update GetIterator bytecode to load and call object[Symbol.iterator]
>
> The functionality of the GetIterator bytecode introduced previously is
> now extended from loading the @@iterator property to calling the property
> as well. This change basically absorbs the functionality of additional
> two bytecodes - Star, CallProperty0 in the GetIterator bytecode.
> Importantly, this change handles the cases of eager and lazy deoptimization
> in the middle of the bytecode, i.e., lazy deopt for LdaNamedProperty and
> eager deopt of the CallProperty0 bytecode, using the continuation builtins.
> This mechanism can work as a template for the future bytecode that require
> handling such inter-bytecode deopt scenario. The tests evaluating the eager
> and lazy deopt scenarios are also included.
