The test reads slack properties after the end of the object. With
FLAG_stress_concurrent_allocation a background thread allocates a lot
of objects and might cause concurrent sweeping which causes a TSAN
race. Since this only happens with this test, disable the test in this

Destroyed large pages can be reallocated before the OS get a chance to
reclaim and clear them. In such cases we will get non-zero memory in a
newly allocated page.
Normal pages are not affected since they are kept in page pools instead
of being freed.
Fix by explicitly clearing the payload when destroying a large page.

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.

Within the inspector we should be consistent about passing the script ID
always as integer, and only convert to String16 when actually needed.
That (a) saves memory (and some runtime overhead) when stashing away
call frames, for example in case of async stack traces, and (b) reduces
confusion which representation to chose.

> SharedArrayBuffer was broken, since the feature could only be enabled
> globally per process, and only if the feature flag is set early enough

> trials work.
>
> The implementation is similar to the callbacks that already exist for
> the origin trials for WebAssembly simd and exceptions.
>
> SharedArrayBuffer is still controlled by the flag
> harmony_sharedarraybuffer. If that flag is disabled, then
> SharedArrayBuffer is disabled unconditionally. On top of that, this CL
> introduces a new flag for enabling SharedArrayBuffer per context. If
> that flag is set, a callback is used to determine whether
> SharedArrayBuffer should be enabled.
>
>
> Note that this only controls whether the SharedArrayBuffer constructor
> should be exposed on the global object or not. It is always possible

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.

This is a reland of 296fa964. The fix is
to dynamically check for alignment instead of relying on
{alignof(ElementType)}. I updated the comment to state that independent
of pointer compression we do not guarantee the alignment that the
compiler assumes (hence we rely on undefined behaviour here).
