Instead of returning nullptr, just always call FatalProcessOutOfMemory
when we cannot allocate more memory.
In a follow-up CL, this should be extended to first try to run a GC and
see if this freed enough memory.
This CL is intentionally minimal in order to make it backmergable.

The unittest for WasmCodeManager needs to be refactored into a
parameterized test, such that each individual (parameterized) test can
die with OOM without affecting other tests.

This extends the Promise#then protector to also guard the intrinsic
%ObjectPrototype%, making it usable for fast-path logic in the
AsyncGeneratorResolve operation, where we can skip the "then" lookup
on the iteratorResult in that case. We also add a corresponding fast-
path to the ResolvePromise builtin itself, which avoids the second
"then" lookup on the async iterator side.

This reduces execution time of the fibonacci-async-es2017-native test
from 186.9ms to 171.2ms, which corresponds to an improvement of 8.4%
in this case.

Remove IsBlockTerminator and introduce InstructionScheduler::AddTerminator in
order to handle block terminator instructions.

Instead of the kBlockTerminator flags, we now rely on Instruction::IsTrap(),
Instruction::IsDeoptimizeCall() and explicitly denoting block terminators
when adding them with InstructionScheduler::AddTerminator().

IsBlockTerminator incorrectly included deopts when they were not at the end of
a block, which meant that an instruction with side effects could have been
reordered with respect to a deopt as the deopt was not identified correctly.

Since the snapshot does not contain deopts, this is not causing any problems
at the moment (the scheduler is only enabled on the snapshot).

For async generators that yield primitives, there's not really a point
in creating temporary promises first, just to immediately fulfill them
with the primitive values passed to `yield`. Instead we can skip those
steps and just directly schedule a PromiseFulfillReactionJobTask to do
the job.

This improves the execution time of fibonacci-async-es2017-native from
around 189ms to roughly 183ms, which corresponds to almost a ~3% boost
here.

With this CL the name of an SFI is either stored directly on the SFI
itself (for uncompiled ones) or on the related ScopeInfo if present.

- Combine scope_info and name field on SFI into name_or_scope_info field
- Change the name of a couple of SFI accessors: name => Name,
  has_shared_name => HasSharedName, set_name => SetName
- Add Runtime::kGetFunctionName due to more complex SFI name accessing
