They're failing due to Inf/NaN differences after the latest clang roll,
skipping for now to keep the tree green. A follow-up CL will likely want
to broaden the expectations for these tests to allow both Inf & NaN in
certain cases.

Enable compaction of objects in the map space during a full GC. So far
pages in the map space were never chosen as evacuation candidates. We
might be able to improve memory usage a bit by also compacting map
space. Luckily for us the marking barrier was already emitted when
updating an object's map word.

This CL adds a new flag FLAG_compact_map_space to easily turn off this
feature again. For now we keep this flag (and with that map space
compaction) disabled by default. So GC behavior does not change with
this CL.

Currently the reconstruction of the shared heap object cache for testing
incorrectly includes the terminating undefined value. Unlike the RO cache
reconstruction, which does not change, the shared heap object cache may be
extended by serializing the live Isolate during testing, so it should skip the
original terminating undefined.

The Descriptor of Builtin defines the allocated machine registers for
its parameters. However, when an argument is in
InterpreterAccumulatorRegister, the Descriptor might require another
machine register holding the the value of this argument and result in a
redundant register-to-register move. This CL avoids this move by
allocating a same register for such argument. It also changes the
assigned registers for Typeof, KeyedLoadIC and KeyedHasIC to align the
use in Baseline Builtins.

With dynamic tiering, the total amount of code generated for a
WebAssembly module decreases significantly. However, the amount of
code space we reserved for generated code has not been adjusted yet.
This CL adds a parameter for dynamic tiering to
EstimateNativeModuleCodeSize. If dynamic tiering is used, then the code
space reserved for TurboFan gets reduced to a quarter of the code space
without dynamic tiering.

Reserving a quarter of the space seems to be still quite generous. Even
Google Earth, seems to use a lot of its code, only needs less than 20%.

- It changes ContextSlotIndex from static to non-static.
- Updates ContextSlotIndex and ScriptContextTable::Lookup to use
  handles, since it is necessary for the NameToIndexHashTable::Add
- Adds a NameToIndexHashTableLookup to CSA.
- Renames LocalNamesIterator to LocalNamesRange and iterates the
  hashtable when local names are not inlined.
