Refactor how embedded pointers are visited.
...
This refactoring (almost) gets rid of the requirement to get the target
object address for an object pointer embedded in code objects. This is
not possible on MIPS as pointers are encoded using two instructions. All
usages of RelocInfo::target_object_address() are (almost) obsoleted by
this change. The serializer still uses it, so MIPS will not yet work
with snapshots turned on.

Improve our simple elimination of hole checks.
...
Currently we avoid checking for the hole value after array loads, if the
result is only used by instructions that definitely deoptimize in case
of the hole value (HChange instructions).
This change performs the same procedure for loading from deleteable/read-only
global variable where we can also avoid the check in the same cases.

Record function call targets, use them for inlining.
...
Introduce a version of the CallFunctionStub that records monomorphic
call targets in a one-element cache in the instruction stream. Use
the cache for inlining attempts in the optimizing backend.
