This CL takes advantage of the z15 `load byte reverse element`
instruction to optimize Simd LoadLane opcodes.

On the simulator we only run `load element` as reversing is
not required.

The --turbo-stats and --turbo-stats-wasm flags are useful but they do
not work on Chromium on Android, given we cannot print on exit of the
renderer process.

To cover all scenarios, we can encode the statistics as a string
argument in the trace format. It's also helpful to see those statistics,
as well as the code kind and function name, when clicking on a slice in
chrome://tracing or perfetto.

As a drive-by cleanup, rename ESCAPE to QUOTE in the JSON serialization
code.

> {NativeModule::AddCode} is a central method that should usually be
> called in batches, where the caller holds a {CodeSpaceWriteScope} for a

> This CL moves us closer to that by removing the scope from that central
> method and instead putting it in callers where it becomes more visible.

to synchronize such an access. An example for this is interrupt
handling.

Ignore TSAN for the methods performing the stack walk. There's no need
to use relaxed atomic reads as same-thread writes are consistent and
for other-thread writes there's no guarantee on what values to observe.

JSFunctionData has a fairly heavy serialized payload, and likewise
consistency validation validates many fields and thus has many
opportunities to fail. We therefore want to avoid or reduce validation
whenever possible.

This CL adds tracking s.t. we know which fields were actually used,
and we limit validation to used fields.

Drive-by: Make serialized_ debug-only.
Drive-by: Don't create deps for context/native_context/shared.

This CL does the following for x64:

- Add seq cst TSAN helpers.

- Refactors codegen's handling of TSAN helpers to also support
  seq cst accesses.

- Perform stores only once instead twice under TSAN, since
  duplicating stores is unsound. Previously this was "fine"
  because all duplicated stores were relaxed. SeqCst stores
  are used for synchronization, however, and duplicating them
  breaks the synchronization.

%TypedArray.prototype% methods that receive a user callback
fn should not break in the mid-way of the iteration when the
backing array buffer was been detached. Instead, the iteration
should continue with the value set to undefined.

Notably, %TypedArray.prototype%.filter was throwing when the
backing buffer was detached during iteration. This should not
throw now.
