This replaces custom Release_CompareAndSwap implementation with a call
to compiler intrinsic / std:atomic, which is TSAN friendly.

The quite common empty object literal doesn't need an AllocationSite
since it starts off with the general ElementsKind. By using a separate
bytecode we can directly instantiate the empty object without jumping
to the runtime first.
Note: this experimentally disables pretenuring for empty object
literals. Depending on the outcome of our benchmarks pretenuring
will be enabled again or fully removed for empty object literals.

This CL introduces 4 tests that verify that the effects of a grow_memory
instruction executed inside a loop are visible also when the loop is over.
The tests verify the output of the current_memory instruction and the
result of loading a variable stored in the grown memory inside the

* the memory is grown inside the loop (no memory operation outside);
* the memory is grown both inside and outside the loop;

For example, when an EnumeratorInterceptor is defined, Object.keys(),
Object.entries(), and Object.values() should all have the
same number of entries.
This CL creates consistent behavior among these
functions. If a QueryCallback is present, it is used to

Currently, Declaration stores a Scope pointer to whichever Scope the
declaration appeared in. This is used to disallow var declarations
being hoisted over lexical declarations. For example:
{
let x;
{ var x; }
}
But in fact this is the only sort of case where storing the scope
is required: for lexical declarations (including function declarations
appearing in blocks), Declaration::scope() was always identical to
Declaration::proxy()->var()->scope(). That is, only var declarations
end up "nested" in this way.
This patch adds a subclass of VariableDeclaration to store the Scope.
Since the only thing that cares about that data is Scope analysis,
this isn't treated as a distinct AstNode::NodeType from VariableDeclaration,
leaving all AstVisitors untouched in the process.
Also reworked the logic in Scope::CheckConflictingVarDeclarations() for
clarity after making changes to accomodate the new code.

Many handlers are not used again, so we can improve the cache hit rate
by caching fewer handlers. Specifically, in this CL, when a StoreIC
miss causes a new map transition to be created, then the handler is not
cached right away yet (it will be cached next time, when the transition
exists already).
Also, fix an embarrassing bug where growing a TransitionArray dropped
cached handlers. That further improves the cache hit rate. ;-)

In LoadElimination, don't consider two fields as potentially
aliasing if they have different names.
This gives another 5% boost on the Octane/DeltaBlue benchmark,
since the redundant loads and checks on the elms of the
OrderedCollection can be properly eliminated in the chainTest.

This CL is a precursor to the callback-based enumeration of frame summaries.
It removes the reliance of FrameInspector on having a cached copy of the
FrameSummary, instead unpacking it to instance variables so that clients
of FrameInspector do not need to get information from two sources
(the FrameSummary and the FrameInspector itself).
