Vector register lane numbers on IBM machines are reversed
compared to x64. For example, doing an I32x4 extract_lane with
lane number 0 on x64 will be equal to lane number 3 on IBM machines.
Vector registers are only used for compiling Wasm code at the moment.
Wasm is also little endian enforced. On s390 native, we manually do
a reverse byte whenever values are loaded/stored from memory to
a Simd register. On the simulator however, we do not reverse the bytes
and data is just copied as is from one memory location to another
location which represents a register. To keep the Wasm simulation
accurate, we need to make sure accessing a lane is correctly simulated
and as such we reverse the lane number on the getters and setters.
We need to be careful when getting/setting values on the Low
or High side of a simulated register. In the simulation, "Low" is
equal to the MSB and "High" is equal to the LSB on memory.
As a result, many of the "#ifdef V8_TARGET_BIG_ENDIAN" blocks on
Simd opcodes are not needed anymore as we are now simulating
native behaviour.

With top-level await, when Evaluate is performed on an already-evaluated
synthetic module, Module::InnerEvaluate returns undefined. This breaks
top-level await's assumption that the returned value is always a
promise.
In order to make SyntheticModule's behavior consistent with
SourceTextModule, the top_level_capability field is moved up to Module
and SyntheticModule::Evaluate places the promise returned from the
host's evaluation steps in that field. Now SourceTextModule and
SyntheticModule can share the same code to handle the case where the
module is either kErrored or kEvaluated, so the code for this
is moved up to Module.
Thus, SyntheticModule is now guaranteed to return the
promise from the evaluation steps even on subsequent Evaluate() calls.
Unfortunately Node hasn't yet updated their EvaluationStepsCallback
to return a Promise, so we can't yet assume that the returned value
is a Promise without breaking Node. So, this change also adds a clause
to check for this condition and create a new resolved Promise if one
was not provided by the callback steps. This could eventually be
removed once Node's callback steps are updated for top-level await.

Previously in https://chromium-review.googlesource.com/c/v8/v8/+/2545573
I updated BasicBlockInstrumentor to use 64-bit floating-point values
rather than 32-bit integers, so that it could never overflow. However,
I've now learned that some builtins (particularly RecordWrite) are not
allowed to use floating-point registers, and so running with
basic block instrumentation enabled could produce incorrect results.
This change switches back to 32-bit integers, but adds saturation logic.

TimeToSafepoint is the time needed for all background threads to enter
a safepoint after the GC was started on the main thread. This CL
improves that metric during concurrent compilation to bytecode by doing:
1) Park the LocalIsolate during
InterpreterCompilationJob::ExecuteJobImpl. There are no concurrent
heap accesses happening while generating bytecode for now. So instead
of manually placing Safepoint() invocations in the code, simply park
the local isolate.
2) Destroy the LocalIsolate before the ReleaseParser operation. I've
seen this take around 2ms, which regressed TimeToSafepoint a lot.
3) Add explicit safepoints to concurrent allocations. This covers the
rest of the code and from what I've seen so far this is good enough
to keep TimeToSafepoint around a few microseconds.
I've still seen TimeToSafepoint events with 20-80 microseconds but those
were quite rare and always seemed to be related to Turbofan.
AsLocalIsolate() is necessary in generic code to convert both Isolate
and LocalIsolate to LocalIsolate.
