The new API supersedes the old `RegisterDefaultSignalHandler` and flag
combination. Now the embedder must explicitly call
`EnableWebAssemblyTrapHandler` to activate the trap handler and optionally
install the default signal handler. The old flag is now used only by D8 to
decide whether to call this function.

The embedders should use the EmbedderGraph API. The similar structure
can be created with the following steps:
1) Create a root node for each retainer info group.
2) Iterate all handles using Isolate::VisitHandlesWithClassIds.
3) Add an edge from the retainer info node to the v8 wrapper node.
4) Add an edge from the v8 wrapper node to the retainer info node.

See how HeapSnapshotRetainedObjectInfo is converted to the new API.

In general, TurboFan doesn't encounter phi nodes with only a single
data input in the backend. However, CSA-based builtins (especially
auto-generated ones, e.g. from Torque), may contain single-input phi nodes,
although outside the auto-generated case this doesn't happen much in practice.

Single input phi nodes (i.e. phis in blocks with one predecessor) don't have
any side effects and are essentially useless and harmless, but to avoid problems
in the backend of TurboFan (whose SSA deconstruction disallows control flow
splits that continue to blocks with phis), this CL tweaks the existing
CSA-only control flow and graph sanitization in the CSA path to ensure
no no-op phis.

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.

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).

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
