Function win64_unwindinfo::RegisterNonABICompliantCodeRange() calls
LoadNtdllUnwindingFunctions() to dynamically load from ntdll a couple of
functions that are not available on Windows 7. Unfortunately there is a
race condition in LoadNtdllUnwindingFunctions() that can cause a crash
when multiple isolates are initialized concurrently.
This can be fixed using base::CallOnce().

Up until now, we cached export wrappers per export index. With the
anyref proposal potentially many more functions will need export
wrappers, e.g. any function that is stored in a table, and any
function accessed by the new ref.func instruction.

With this CL, we change the caching scheme an do the caching per
signature. Thereby we can guarantee that any export wrapper which
potentially exists can be stored in the cache.

For cctests which use wasm-run-utils, we don't know the size of the
cache anymore ahead of time. However, we assume that no more than
5 signatures will be used in any cctest. If this assumption is not
true, we can just adjust the number.

The cache is now accessed in all code paths where we need an export
wrapper.

KeyedStoreIC computes the expected transition to the map based on the
incoming receiver map, the index and the value that is being stored.
Since we already store the element into the object, the runtime would
have already computed these transitions and it is possible to use the
new map of the object instead of recomputing the map. Though we would
need additional checks to see the newly transitioned map is indeed
a more generic elements transition and not an unexpected transition.

FindElementsKindTransitionedMap checks if we could transition from
the source map to one of the target maps without requiring any instance
rewriting. It does this by replaying all the property transitions of the
source map on each elements kind map and seeing if it needs a instance
rewrite. Since we already know the elements kind of the target maps, we can
avoid doing this for element kinds that are not in target map.

Provide a global memory controller used to compute limits for combined
on-heap and embedder memory. The global controller uses the same
mechanism (gc speed, mutator speed) and growing factors as the regular
on-heap controller.

Rely on V8's mechanisms for configured state that stops shrinking the
limit.

- API fixes with overrides and default versions.
- Fix of depending on uninitialized values when using the old API.
- GCTracer: Fixed issue in speed computation.

KeyedAccessStoreMode is used when creating store handlers to determine
which cases to handle (ex: handle cow, grow) and hence choose an
approriate builtin. It is also used to specify elements kind transitions
which is used when computing ic transitions. The store mode and the
transition mode are independent of each other and it would be cleaner to
use different enums to represent them. This also reduces the total number
of cases in each enum.

This is a border case that appeared in one of our tests. It seems a good
idea to test for it. It does not seem to be common enough to handle it
specifically (i.e replacing the Word64Equal with a true bool constant)

The HandleApiCall uses BUILTIN_EXIT frames now instead of EXIT frames,
so API calls show up in stack traces. We no longer need API builtins
and this CL removes them and the corresponding C++ macros.

This is mainly a torque change, but as a drive-by we get rid of
kStartOfPointerFieldsOffset
kEndOfTaggedFieldsOffset
which often are used to enclose a section of pointers in an object.
