Improve x32 detection macro.

When targeting the Microsoft ABI in 64bit mode, clang defines __x86_64__ but
doesn't define __LP64__ (Microsoft uses LLP64), so it would fall down the x32
path. cl.exe doesn't define __x86_64__ in the first place, so it didn't have
this problem.

Rather than trying to guess pointer size by looking at __x86_64__ and __LP64__,
check for pointer size directly using __POINTER_SIZE__. This is defined by both
gcc and clang, and eliminiates this problem.

This should fix hundreds of "error(clang): unknown type name 'Atomic64'" when
compiling v8 on Windows with clang for 64 bit.

of code stubs are too complex to be described this way, and
they are encoded with the macro
DEFINE_NULL_CALL_INTERFACE_DESCRIPTOR().

Along the way:
* allowed inheritance of CallInterfaceDescriptors.
* Defined static Register methods for some of the new
  CallInterfaceDescriptors. We could go a lot further here, but
  it doesn't have to be done immediately.

  updates (which are very common) now stand out less than they did,
  making the less-common (and arguably more important) debug
  announcements appear brighter.
  - FP registers and values are now magenta.
  - Integer registers and values are now cyan.
  - Memory accesses are now blue.
- LOG_WRITE prints the source register for stores.
- Loads are logged with a format similar to that used for stores.
  Specifically, the memory address is printed alongside the new register
  value.
- Updates to D registers print the raw bits as well as the double value.
  Updates to S registers print the raw bits as well as the float value.
  (Previously, we printed both double and float interpretations of the
  bits, which was a bit cluttered.)
