Using uint8_t[] causes decay to pointer issue, which manifests in
copying garbage values in the call to WriteLittleEndianValue. Change it
to use a std::array, which doesn't have the decaying behavior.
Also add a regression test from comment#6 of the linked bug.

On desktop systems, we use a very basic tiering strategy: Everything is
initially compiled with Liftoff, and once that is done, the module can
start being used. Concurrently to the execution, we re-compile all code
with TurboFan, and hot-swap each function once TurboFan finishes.
We should start using a more dynamic strategy where each function is
tiered-up when judged necessary. This change will then tier-up each
liftoff function once it has been called 5 times.
I then added a counter in the native module, that is updated directly
from Liftoff code, and a runtime call is then made when the counter
reaches the goal.

With work on NCI proceeding, it makes sense to test multiple
pipeline configurations.
The nci variant (passes --turbo-nci) now spawns dedicated NCI
compilation jobs and inserts generated code into the code cache.
The nci_as_highest_tier variant (passes --turbo-nci-as-highest-tier)
simply replaces TF with NCI code (no extra jobs, no extra caching).
This mode stresses NCI generated code more than the nci variant, in
which NCI code only runs on cache hits.

The {operator==} on {VarState} did not check the spill offset, so when
merging stack states, we forgot to move stack values if both source and
destination were stack slots, but at different offsets.
This CL fixes this by removing the {operator==}, because the semantics
(and use) are not clear, and it's only used in one place anyway.
The equality check was mostly redundant, so inlining it also makes the
code smaller and faster.

The snapshot code assumes that the entire snapshot's length fits into
an int, which implies that it doesn't support individual objects that
are bigger than that. That's okay, because it isn't reachable from
user code, and embedders would notice at compile time when they run
into this limit. So we can just continue to skip the few regression
tests we have for huge TypedArrays in the stress_snapshot variant.

For 64-bit binary operations, Liftoff on arm made the assumption that
register pairs are always ordered, i.e. the register code for the low
word is lower than the register code for the high word.
Ensuring this was only implemented in {GetUnusedRegister} in
https://crrev.com/c/2168875. Other cases were missing though, e.g.
return values, but also different places were we
construct register pairs internally.
Thus, this CL removes this constraint again and instead handles
unordered register pairs in 64-bit binary operations on arm.

We implement this by returning InsufficientFeedback from the heap

The IsInBounds function is used in a few different places, when used for
bounds checks on 32-bit platforms, size_t for max_memory_size leads to
incorrect out of bounds accesses as size_t is not guaranteed to be
64-bit on all platforms. Use specific uint32_t, uint64_t methods for
Wasm bounds checking instead of size_t.

Due to recent spec changes, this CL removes the type immediate of
ref.is_null again. Instead we check if the type of the input parameter
is nullable.

Just a test for now to document how trailing space after async
functions is not removed by SourceRangeAstVisitor.

Adjust atomics.wait, atomics.notify semantics for when they are used
with non-shared Wasm memory to mirror the spec change introduced
in: https://github.com/WebAssembly/threads/pull/147. This does not
need to be gated by the flag here, as this will only decode if
the flag is enabled.
