5fba4891de More aggressive reuse of spill slots in the register allocator.
Two improvements:
- At phi nodes, we now try to merge operands into one spill slot and
  then reuse the spill slot for the phi.
- After register allocation we merge disjoint spill slots.

With this change, I see about 4% improvement in zlib.

9514d34e14 Refactoring InterfaceDescriptors away from code-stubs.h
Clean up and create seperation between the concept of a call descriptor and a
code stub interface descriptor. The former is just concerned with how to call,
but the latter has many extra hints related to code generation and
deoptimization for the implementation of a particular code stub.

90c8932596 Replace our homegrown ARRAY_SIZE() with Chrome's arraysize().
Our own ARRAY_SIZE() was pretty bad at error checking. If you use
arrasize() in a wrong way, the compiler will issue an error instead of
silently doing the wrong thing. The previous ARRAY_SIZE() macro is still
available as ARRAYSIZE_UNSAFE() similar to Chrome.

018ef484b9 More OStreamsUse OStreams more often.
This is a mostly mechanical CL (more than 90% Emacs macros and
query-replace-regexp) moving FILE*/StringStream*-based APIs to
OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and
incrementally cleaned up later.
