With the value stack refactoring in 1b5c7e15 / r73193, the
combination of helper functions called by PeekArgs() ended
up checking the stack height repeatedly. This CL avoids that
by introducing a ValidateArgType() helper that does not check
stack height.
Bonus: achieve a small speedup by special-casing two of the
most common opcodes in the decoder's main dispatcher.

This is a reland of a8b61ef5

The main reason for the revert was not related to this CL and was fixed
with https://crrev.com/c/2739646
In addition debug output in d8.test.verifySourcePositions was removed
due to TSAN complaints.

Original change's description:
> [sparkplug] Change bytecode offset mapping and introduce iterator.
>
> Previously, we recorded pairs of (bytecode offset, sparkplug pc) to
> create a mapping of bytecode offset <-> sparkplug pc.
> These pairs were only recorded after builtin/runtime calls.
> In preparation for deoptimizing to Sparkplug, we need a more precise
> mapping.
> With this CL, we record positions for every bytecode. Instead of storing
> a pair of (bytecode offset, sparkplug pc), we store only the pc,
> calculating the bytecode offset from the index in the mapping table.
> For easier use an iterator to access the mapping is introduced.
>
> Drive-by: Reduce sampling interval in cpu-profiler cctest to get rid of
flaky failures.

allow that function to return false if a sparkplug compilation
fails. Similarly, don't assert that --always-sparkplug requires
a function to have baseline code, in case a previous sparkplug
compilation failed.

This change relands the last part of https://crrev.com/c/2601880 .

ScopeInfo has a vestigial 'length' field from when it used to be a
FixedArray. This change removes that field, which saves some memory.

More specifically:

- Make ScopeInfo inherit from HeapObject, not FixedArrayBase which
  supplied the 'length' field.
- Change FactoryBase::NewScopeInfo to allocate the updated object shape.
  It maintains the existing behavior of filling the newly-allocated
  object with undefined, even though that's not a valid ScopeInfo and
  further initialization is required.
- Change a few length computations to use HeapObject::kHeaderSize rather
  than FixedArray::kHeaderSize.
- Remove an unnecessary heap verifier function.

This CL is part of a series that makes SwissNameDictionary available
as a new property backing store. Previously, the flag
v8_dict_mode_prototypes allows selecting between NameDictionary and
OrderedNameDictionary as the backing store used for all dictionary
mode objects. This series of CLs changes this such that enabling the
flag causes SwissNameDictionary being used instead of
OrderedNameDictionary. The behavior for when the flag is not set
remains unchanged (= use NameDictionary).

This particular CL just collects many small changes, including some
CSA changes where runtime calls are necessary.

We sometimes have a need to check for termination requests
while we're in the middle of non-GC-safe computations, so
we can't do a full "HandleInterrupts" (which could do GC).
This CL adds a separate function to check for termination
requests (but no other interrupt reasons) in such cases.
