[cfe-users] Integrated assembler, -arch i386 and ILP32

[Jeffrey Walton via cfe-users]

> BOOL_X32 is set when __ILP32__ is defined. BOOL_X86 is defined when
> __i386__ (and friends) is defined. BOOL_X64 is defined when __x86_64__
> (and friends) is defined. We set the conditions based on " System V
> Application Binary Interface, AMD64 (With LP64 and ILP32 Programming
> Models)", http://sites.google.com/site/x32abi/documents/abi.pdf.

Forgot to mention.... I believe "OS X ABI Function Call Guide" [1] is
Apple's controlling document, but it does not mention the define.
