We don't want to handle even non-growing stores when there are TypedArrays
in the prototype chain. Typed arrays handle the out-of-bounds accesses by
ignoring the stores unlike the regular array writes. We just let runtime
handle these cases instead of making ICs more complex.

There was an earlier cl (https://chromium-review.googlesource.com/c/v8/v8/+/1609790)
that fixed it for growing stores. This cl extends it for non-growing stores
as well to handle more cases.

This CL renames jsregexp.{h,cc} to regexp.{h,cc}, hides all non-public
functions of RegExpImpl in the .cc file, and renames the public parts
of RegExpImpl to just RegExp. Include directives from outside the
src/regexp directory are limited to regexp.h, regexp-stack.h, and
regexp-utils.h. We also expose all result codes that can be returned
by irregexp code (including RETRY) on the public header since they
are needed elsewhere, e.g. in builtins.

This adds missing support when converting a Word32 value (either in
Signed32 or Unsigned32 range) to Word64 representation, for which the
type also includes MinusZero. This conversion is fine as long as the
difference between 0 and -0 is not observable (in other words, as long
as the truncation identifies zeros).

This function was functionnaly equivalent to FreeList::TryFindNodeIn.

They probably were different when FindNodeIn was iterating through
the empty FreeListCategories, but since CL 1648476, FreeListCategories
in the FreeList can't be empty, and there was therefore never more than
a single iteration of FindNodeIn's while loop.

This CL allows CsaLoadElimination to retain some information in the presence of StoreToObject nodes. Two stores to an object don't alias if either the objects or the offsets don't alias. The analysis approximates either of these two conditions conservatively as follows:
- Freshly allocated, distinct objects cannot alias.
- Two objects cannot alias if one of is freshly allocated and the other was passed as a parameter or is a heap constant.
- Two offsets cannot alias if they are both constant and distinct from each other.

This change removes the special case in the Torque compiler for types
that descend from JSObject: they will no longer get implicit
"| Undefined" appended to their types for verification purposes. It
removes any additional custom verification steps in objects-debug that
are made redundant by that change.

In order to do so safely, I categorized all cases where we were
implicitly adding "| Undefined" to the field type, as follows:

1. Classes that aren't using the generated verifier function (we should
   probably revisit these, but for now we at least know they're safe):
   - JSGlobalObject
   - JSFinalizationGroup
   - JSFinalizationGroupCleanupIterator

2. Classes where the existing verifier is already at least as strict as
   what we would get after removing the implicit "| Undefined":
   - JSDate
   - JSPromise
   - JSRegExp
   - JSRegExpStringIterator
   - WasmMemoryObject
   - JSWeakRef
   - JSStringIterator
   - WasmExceptionObject
   - JSListFormat (fixed in part 1)
   - JSPluralRules (fixed in part 1)
   - JSRelativeTimeFormat (fixed in part 1)
   - JSSegmenter (fixed in part 1)
   - JSArrayBufferView (fixed in part 1)
   - JSTypedArray (fixed in part 1)

3. Classes where, to the best of my knowledge based on code inspection,
   we already initialize the object correctly to pass the new stricter
   generated verifier:
   - JSFunction
   - JSArrayIterator
   - JSMessageObject
   - JSBoundFunction
   - JSAsyncFromSyncIterator
   - WasmModuleObject
   - JSAsyncFunctionObject

4. Classes that needed some adjustment to their initialization order to
   avoid exposing uninitialized state to the GC:
   - JSArray (only in Factory::NewJSArray; Runtime_NewArray and
              CodeStubAssembler::AllocateJSArray already behave fine)
   - WasmTableObject
   - JSDateTimeFormat
   - JSNumberFormat
   - JSCollator
   - JSV8BreakIterator
   - JSLocale
   - JSSegmentIterator
   - JSModuleNamespace

5. Classes that had incorrect type definitions in Torque:
   - WasmGlobalObject (category 4 after correction)

6. Classes that weren't fully initialized due to bugs:
   - JSGeneratorObject
   - JSAsyncGeneratorObject

regexp API file, currently still named jsregexp.h.

* Move JSRegExp::Flags convenience functions to regexp-compiler.h.
* Set RegExpImpl methods private if possible (these will later be
  moved to a new hidden impl class).
* Merge RegExpEngine::CompilationResult into RegExpCompileData.
* Move remaining RegExpEngine methods to RegExpImpl and delete
  RegExpEngine.
* Extract RegExpGlobalCache.
* Document a few data structures.

Upcoming CLs will rename RegExpImpl to RegExp and jsregexp.h to
regexp.h. This should then be the only header included from other

This adds preliminary support for storing constructed WebAssembly
functions in tables. Note that for now only tables at index #0 are
supported, extending it to other tables indexes will be done as a
follow-up.

This refactors the constant pool handling for arm64. The immediate goal
is to allow 32bit compressed pointers in the pool. The mediate goal is
to unify the implementation with the arm constant pool, which will be
done in a follow-up CL.

The functions

 * JSCallReducer::ReducePromisePrototypeThen
 * JSCallReducer::ReducePromisePrototypeFinally
 * JSCallReducer::ReducePromisePrototypeCatch

need the prototype for all receiver maps to be serialized in order
to take effect. We can do this by processing our receiver hints
when processing a builtin call in the serializer.
