This relands squashed CLs:
59b9aaf7db8f84d0bb8f
The revert was at crrev.com/c/2996198.
Changed: Fixed a test in which bytecode flushing caused a behavioral
change between serialized- and unserialized SFI Refs. The serialized
SFI ref kept bytecode alive while unserialized SFIs allow flushing.
The test was fixed by adding a %PrepareFunctionForOptimization
annotation.

FLAG_SCOPE_EXTERNAL can be used outside of the v8::internal namespace,
while FLAG_SCOPE can not.
This CL refactors FLAG_SCOPE such that it can be used anywhere, and
removes the redudant FLAG_SCOPE_EXTERNAL macro.
Also, UNFLAG_SCOPE_EXTERNAL is removed in favor of FLAG_SCOPE_VAL, as
the word "flag" in the macro name is meant to refer to a flag, and not
to the verb or action of "flagging" something, hence "unflag" does not
match the terminology.

GetPropertyCell was implemented as:
LookupIterator it(holder, isolate, name, LookupIterator::OWN);
it.TryLookupCachedProperty();
if (it.state() == LookupIterator::DATA) it.GetPropertyCell();
Due to concurrency requirements, we essentially have to reimplement
this entire path for use in a concurrent setting:
- Reads in some cases have to use relaxed or acquire semantics.
- The IsPendingAllocation predicate must be called on some objects
before reading into them.
- Repeated reads of the same field must be avoided due to the
possibility of concurrent modifications.
This CL introduces two new methods:
ConcurrentLookupIterator::TryGetPropertyCell implements the outer
lookup logic, including the repeated lookup for accessors / cached
property names.
GlobalDictionary::TryFindPropertyCellForConcurrentLookupIterator is a
slightly modified HashTable::FindEntry which follows the above rules.

Adds support for a seperate dynamic map checks trampoline that takes the
feedback vector as an argument rather than reading it from the stack
frame, to enable it to work for inlined functions. Plumbs the logic
through the compiler to select between these trampolines based on the
framestate.

This flag only controls whether d8 installs the signal handler for wasm
traps. Hence it should be a d8-only flag, to avoid confusion if used in
other embeddings.
We just introduced --wasm-enforce-bounds-checks to do what you might
think --no-wasm-trap-handler would do.
