Reuse the existing builtin and extension infrastructure to provide a
garbage collection mechanism that allows for asynchronous execution.
On --expose-gc, this changes the gc call to parse parameters the
following:
(1) Parse options when encountering an options object with known properties.
(2) No parameters is parsed as
{type: 'major', execution: 'sync'}.
(3) Truthy parameter that is not setting options is parsed as
{type: 'minor', execution: 'sync'}.
(2) and (3) preserve backwards compatibility for existing callers as this may be
used widely across various test and benchmarking infrastructures.
Valid options:
- type: 'major' or 'minor' for full GC and Scavenge, respectively.
- execution: 'sync' or 'async' for synchronous and asynchronous
execution respectively.
Returns a Promise that resolves when GC is done when asynchronous execution
is requested, and undefined otherwise.
Note: This is implemented as builtin to avoid having any stack at all. This
information is also passed to the embedder to allow skipping stack scanning.

Rather than duplicating code paths for in- and out-of-object stores,
have one code path which checks whether it needs to load the property
store (and change the storage location to the HeapNumber value for
unboxed doubles).
As a drive-by, change the representation dispatch into a switch, and
inline the representation checks into that switch, to make explicit
what checks for what and which paths transform the value. Also, TNodify
some of the surrounding functions.

Original Commit Message:
Stack overflow checks are typically implemented as part of the TurboFan
graph of a function. This means that the stack check code is executed
after frame construction. When a frame is too big, though, there may not
be enough space on the stack anymore to throw the stack overflow
exception after frame construction. With this CL we do an additional
stack check before frame construction for functions with big frames.
As discussed offline with mstarzinger, I do this change currently only
for WebAssembly.
This CL contains only the changes for arm. I will do the other platforms
in separate CLs

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.
