The emitted safepoint entries had the wrong size, because it did not
contain StandardFrameConstants::kFixedFrameSizeAboveFp. The code still
worked because the indices of encoded in the entries where too low by
StandardFrameConstants::kFixedFrameSizeAboveFp and thereby corrected
the invalid size. It worked as follows:
First the stack_slots_size gets calculated from the safepoint entry.
Then the position of a stack slot was
"frame_header_base + stack_slots_size - index * pointer_size", where
"index" is what is encoded in the safepoint map. Because of the incorrect
encoding, both stack_slot_size and index were too low by
StandardFrameConstants::kFixedFrameSizeAboveFp. Therefore the errors in
both values eliminated each other, making the end result correct.
With --print-code, the safepoint entry size was also read, and it
crashed because the encoded value was too low.
The reland fixes the indices.
Original message:
With this CL we emit safepoint maps for externref values on the Liftoff
value stack. With that there is support for externref parameters and
locals in Liftoff, as well as for intermediate values of type
externref.

tools/debug_helper:run_mkgrokdump used to only depend on mkgrokdump.
However, the snapshot can change without affecting the mkgrokdump
binary itself. So, if the mkgrokdump binary doesn't change, then
run_mkgrokdump doesn't run, even if the snapshot changed.
This could cause mysterious test failures in incremental builds, in
particular for tests testing the contents of heap-constants-gen.cc.
Now, we make run_mkgrokdump depend on run_mksnapshot_default
directly, so that snapshot updates force an mkgrokdump run.

1) Strengthen the ObjectData::As* cast methods to check that the kind
is kSerializedHeapObject, because otherwise the data object is not
a subclass instance and the cast is invalid.
2) Fix errors revealed by (1) and pave way for moving away from
serialization. These changes are mechanical except for a needed
refactoring of ContextRef::previous.
Details regarding (2):
Change (1) revealed a large number of places where we incorrectly casted
object data. This went unnoticed so far because in the end we accessed
the object through the corresponding ObjectRef interface which did the
right thing depending on the data kind.
These bugs were introduced when kUnserializedReadOnlyHeapObject was
added, but they also affect the new kNeverSerializedHeapObject and would
become show stoppers as we move more objects to the latter kind. The CL
fixes all the issues that I found except one:
There's still one place left where we assume a particular subclass
instance for now (marked with a TODO). This is not a bug at the moment
but will cause CHECK failures once we move the corresponding object type
to never-serialized. A rewrite of map serialization might be needed to
resolve that.
Note:
With the changes in (2) we lose some type safety in the implementation
of the *Data classes. With some extra work that could be avoided.
However, I think it's not worth it because (i) these classes are
expected to be removed (and in the meantime to not change much), and
(ii) their wrapper *Ref classes still ensure type safety.

Previously to this commit only quantifiers of the form /<x>*/, i.e.
arbitrarily often greedy repetition, were implemented. Now a much
larger class is supported, e.g. + and ? and their non-greedy variants.
Because it came up repeatedly during the implementation, the commit also
adds the Label and DeferredLabel classes to patch JMP and FORK target
addresses more easily.
Still not supported are the following quantifiers:
- Possessive quantifiers, where I'm not entirely sure whether they could
be implemented in principle. Re2 doesn't support them.
- Quantifiers with large but finite numbers for min and max numbers of
repetitions, as in e.g. /<x>{9000, 90000}/. These are currently
limited to some small value. This is because the body of such
repetitions is unrolled explicitly, so the size of the bytecode is
linear in the number of repetitions.

We need to also check SIMD support for v128.const and i8x16.shuffle,
these are separate functions, not part of the SimdOp or SimdLaneOp.
This was discovered while running some JS tests when trying to stage
SIMD.

Change FeedbackVector into a Torque-generated class, simplifying its
C++ implementation. As a drive-by, also get rid of the lower-cased,
integer-indexed slot accessors, and replace the calls that needed this
integer index with FeedbackSlot (potentially with a new WithOffset
adjustment for extra data slots).

Original Commit Message:
With this CL we emit safepoint maps for externref values on the Liftoff
value stack. With that there is support for externref parameters and
locals in Liftoff, as well as for intermediate values of type
externref.

No yielding is necessary since the main thread Join()s.
max concurrency is determined based on either

The wasm interpreter is slow on an arm simulator build with asan when
it comes to return calls. An infinite return-call recursion therefore
caused a timeout on ClusterFuzz. With this CL we increase the costs of
return calls, and thereby avoid the timeout.

The parameters should be processed and evaluated in an increasing order
(starting with the 1st param).
Before we started with the last (n-th) parameter which was not correct.
