This is the second reland of 4683d6fe52
Initial CL: crrev.com/c/2874663
First reland: crrev.com/c/2886861
The first reland fixes Ref construction failures in:
- MapRef::instance_descriptors
- NativeContext reads (see also crrev.com/c/2891575)
The second reland (this CL):
- Adds required infrastructure (e.g. kAssumeMemoryFence) but
without enabling the IsPendingAllocation check. Enabling the check
will be done separately to avoid further revert chains.

Loop unrolling did not work properly with floating control. Seeing as
very few spots in the wasm compiler introduced floating control, we
decided to disallow it altogether.
Changes:
- When lowering 64-bit rol/ror/clz/ctz in 32-bit platforms, we use a
diamond operator, which used to introduce floating control. This CL
adds a control edge to these operators so that the diamond can be
chained to that control instead.
- During loop analysis, as an additional safety check, we check that the
explored loop does not have floating control. Exceptionally, floating
control pointing directly do start() is allowed.
- Change wasm-compiler so that generated floating projections point to
start() even after stack check patch-in.

When a function is invoked by prototype.apply, it may undergo following transformation in the JSCallReducer:
receiver.apply(this, args) ->
this.receiver(...args) Since the new target (also the receiver of apply()) is not collected to the feedback slot, further speculative optimization on the new target is not available if the new target
is not a heapconstant.
With this CL, the receiver will be collected to the feedback instead of the target if the target is a prototype.apply. It may improve the performance of the following usecase by ~80%.
function reduceArray(func, arr, r) {
for (var i = 0, len = arr.length; i < len; i++) {
r = func.apply(null, r, arr[i]);
}
return r;
}
var a = 0; for (var i = 0; i < 10000000; i++) {
a += reduceArray(Math.imul, [5,6,2,3,7,6,8,3,7,9,2,5,], 1);
}
console.log(a);
This CL also improves the runTime score of JetStream2/richards-wasm by ~45% in default, ~60% with --turbo-inline-js-wasm-calls.

For copying the SharedArrayBuffer content, we cannot use a simple
{memcpy} because that produces data races with thread concurrently
modifying the content. Instead, use a custom {Relaxed_Memcpy} that uses
proper relaxed atomics. The implementation is slightly optimized to do
word-sized loads and stores where possible. If we still get performance
regressions, we can optimize it further in follow-up CLs.

We potentially emitted the same gap move multiple times to satisfy slot
constraint of live ranges defined by a constant. Avoid this by keeping
track of already spilled ranges for a given instruction.
This is not expected to cause any regression because this case is rare.
If it does, a better approach to save allocations would be to re-use the
same vector by storing it somewhere that survives the function calls,
e.g. in the ConstraintBuilder.
Drive-by: Remove unused functions.

Element segments and tables in tests used an ad-hoc mechanism to
describe the different types of initializer expressions, e.g. an number
which could denote either the value of a constant or the index of a
global. This CL tidies up and generalizes the test infrastructure by
directly using WasmInitExpr in those cases.
Additional changes:
- Introduce WasmElemSegment class.
- Remove obsolete --experimental-wasm-bulk-memory flag from tests.
- Rename WasmInitExpr.type -> kind.
- Remove dependency of wasm-module-builder from mjsunit.js (except in
assertTraps).

This CL factors out a CodeRange class out of MemoryAllocator.
When V8_COMPRESS_POINTERS_IN_SHARED_CAGE is defined, there is a single
CodeRange shared by all Isolates in the process. This also turns short
builtins back for both configurations of pointer compression. When
sharing a cage, there is a single copy of the re-embedded builtins.
Since a shared pointer cage is still experimental, to avoid API churn
this CodeRange's size is not configurable and is always the maximal size
depending on the underlying platform.

Changes:
- Add WasmInitExpr class which knows how to create initializer
expressions as pairs of {type, value}. Also define a default for every
type. Emit such pairs to a byte array with emit_init_expr().
- Add an initializer expression to every global (addGlobal() uses the
default if the argument is absent).
- Introduce wasmI64Const();
- Update tests as needed.

The previously added perf-context Promise-hooks take a v8::Function as
arguments. However, the builtin code was only accepting JSFunctions
which causes cast errors.
Drive-by-fix: Directly pass nativeContext in more places.

With --stress-scavenge it is possible that we don't have a memento for
the object we are interested in anymore, making the test useless.

* Failed tests that also trigger GCs are not filtered out. They are
expected to be fixed when TPH supports real garbage collection.
