If b is S128Zero, Shuffle(a,b,s) can be optimized to
Swizzle(a,s). By setting s[i] to 0x80, we can avoid access b.
If a is S128Zero, we can swap a and b first.

If one input of I8x16Shuffle is S128Zero, this patch can save
~60% instructions(7 of 12), and more than 30% improvement is
observed in local microbenchmarks.

The test cctest/test-v8windbg recently started failing because the
v8windbg debugger extension is unable to read the "flags" field on a
SharedFunctionInfo instance. This occurs because one of the bitfields
within "flags" has type OSRCodeCacheStateOfSFI, which is only declared
using an "opaque enum declaration":

  enum OSRCodeCacheStateOfSFI : uint8_t;

When WinDbg fails in its attempt to look up that type, v8windbg responds
by failing to construct anything at all for "flags". However, the other
17 bitfields in "flags" can be represented successfully, so a more
useful behavior is to just skip the one failed entry.

In particular use the same "location" in any call site to make grouping
OOMs easier. Move the detail information into the new OOMDetails struct.

Since we cannot construct OOMDetails via "{.detail = ...}" yet (C++20),
we add another variants of FatalProcessOutOfMemory which receives the
detail string and internally stores it in an OOMDetails struct.

This is a follow-up CL to https://crrev.com/c/3623542.

When updating pointers during a full GC, a page might not be swept
already. In such cases there might be invalid objects in free memory.
Since these objects might be dead, their maps might have been reclaimed
already as well.

The previous CL cached the size of invalid objects in order to avoid
accessing an invalid object's map. However, as soon as a slot is within
an invalid object, we also need to check whether this slot is still a
tagged pointer which would require map access. This CL checks marking
bits on invalid objects to skip that check on such invalid objects.

Split off a TurbofanFrame from OptimizedFrame, and make MaglevFrame a
subclass of OptimizedFrame. This allows it to be treated as an optimized
frame by code that is looking at deoptimization data.

NumFuzz passes various flags to V8 testing randomly, which can lead to
various flag contradictions with existing flags. Up to now the system
ignored the check for contradictions and kept running the test cases,
leading to false positives.

This change adds a new v8 flag --exit-on-contradictory-flags that
exists gracefully when a contradiction is detected. On the numfuzz
side we now filter simple contradictions beforehand.

Measurements showed that ~2% of all numfuzz tests ran into
contradictions. Around half of them are simple contradictions
(repetitions and inversions), which are now filtered beforehand.
The remaining ones (redundant or contradictory implications) are
now ignored.
