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.

Added CallInterfaceDescriptors to all code stubs. A handful
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.

  benefit from this knowledge.
