This cl: https://chromium-review.googlesource.com/c/v8/v8/+/1421077
changed the implementation of SetProperty to infer the language mode.
Language mode is only required when there is an error to decide if we
have to throw an error or not. However we used to compute language mode
eagerly for PropertyCallbackInfo. This causes regressions in some
benchmarks. This cl changes it by deferring it further by computing
it only when it is actually required.

TracedGlobal integrates with the use case of EmbedderHeapTracer and replaces
regular weak Global or Persistent nodes for such cases. This allows to simplify
the case for regular weak handles in a sense that they follow regular weak
semantics (if the underlying object is otherwise unreachable the weak handle
will be reset).
TracedGlobal requires slightly different semantics in the sense that it can be
required to keep them alive on Scavenge garbage collections because there's a
transitive path that is only known when using the EmbedderHeapTracer.
TracedGlobal accomodates that use case.
TracedGlobal follows move semantics and can thus be used in regular std
containers without wrapping data structure.
The internal state uses 20% less memory and allows for only iterating those
nodes when necessary. The design trades the virtual call when iterating
interesting persistents in the GC prologue with calling out through the
EmbedderHeapTracer for each node which is also a virtual call. There is one less
iteration over the set of handles required though and the design is robust
against recursive GCs that mutate the embedder state during the prologue
callback.

https://crrev.com/c/1343709 fixed GetIncumbentContext to work
with ASan, however, GetIncumbentContext didn't work well with
MSan because MSan uses a simulator which supports yet another
separate stack frame.
This patch fixes GetIncumbentContext so that it works well
with not only ASan but also MSan simply following the same way
as v8::TryCatch does.
i::GetCurrentStackPosition() solves the issue of ASan and
SafeStack (native but separate stack frame), and
i::SimulatorStack solves the issue of MSan (simulator stack
frame).

A spec change to simplify IsRegExp has been proposed:
https://github.com/tc39/ecma262/pull/1318
This CL adds use counters for cases in which the spec change would
alter behavior:
1. o[@@match] is trueish but o is not a JSRegExp
2. o[@@match] is falseish (but not undefined) and o is a JSRegExp
This is the V8 side of required changes.
The Chromium-side CL: https://crrev.com/c/1360730
Drive-by: TNodeify IsRegExp.

A WasmModuleObject represents an instance of WebAssembly.Module. It is
called WasmModuleObject internally, so also use that name externally.
We still have a typedef for WasmCompiledModule which will be deprecated
once chromium has been updated to use WasmModuleObject.
