When eagerly evaluating native accessors in the inspector, treat
rejected promises the same way that we treat exceptions, and also make
sure to mark them as handled, so they are not logged as unhandled
promise rejections by Chromium.

We add ref.func and ref.is_null to the fuzzed module.
ref.is_null returns i32, so it is added to i32 generator.
ref.func is added to GenerateOptRef.
GetRefType function is added to generate reftypes.

The fast_call_count getter in d8 was not properly initialised as
throwing when called as a constructor. As a result, it was possible
to pass a new object as its `this` and then attempt to "unwrap" it,
resulting in reading OOB in the new object. This CL also strenghtens
slow_call_count and reset_counts and adds a regression test.

This moves every single class/function out of include/v8.h into a
separate header in include/, which v8.h then includes so that
externally nothing appears to have changed.

Every include of v8.h from inside v8 has been changed to a more
fine-grained include.

Previously inline functions defined at the bottom of v8.h would call
private non-inline functions in the V8 class. Since that class is now
in v8-initialization.h and is rarely included (as that would create
dependency cycles), this is not possible and so those methods have been
moved out of the V8 class into the namespace v8::api_internal.

None of the previous files in include/ now #include v8.h, which means
if embedders were relying on this transitive dependency then it will
give compile failures.

v8-inspector.h does depend on v8-scripts.h for the time being to ensure
that Chrome continue to compile but that change will be reverted once
those transitive #includes in chrome are changed to include it directly.

when trying to figure out whether a node needs to be destroyed. This
preserves the non-atomiticity of the actual pointer which highlights
races using TSAN while fixing destruction.

Combining parts in a balanced-binary-tree like order allows us to

Whenever we are adding a new AddressRegion to the CodeMap, we first
remove all overlapping regions. The logic to check for overlapping
region is incomplete. For example, if all existing regions are less than
the region to be added, we incorrectly remove all regions, effectively
deleting all JITCodeEntry we have constructed.

We extract this overlapping check into a helper function, so that we can
unittest this without worrying about JITCodeEvent functionality, and also
without dealing with V8 internals (like Isolate and SFI).

The overlapping logic is rather hard to understand, has many special
cases, it will probably be much easier to just loop through all the
entries, rather than using lower_bound. Ideally, we can refactor this to
use some sort of sweep-line algorithm. Hopefully the unittests catch the
most obvious cases.

This CL adds an AtomicMemoryOrder parameter to the various atomic load
and store operators. Currently only acquire release (kAcqRel) and
sequentially consistent (kSeqCst) orders are supported.

Additionally, atomic loads and stores are extended to work with tagged
values.

This CL is a pre-requisite for supporting atomic accesses in Torque,
which is in turn a pre-requisite for prototyping shared strings.
