AK: Add Platform.h with an ARCH() macro.

Browse Source 
You can currently use this to detect the CPU architecture like so:

    #if ARCH(I386)
        ...
    #elif ARCH(X86_64)
        ...
    #else
        ...
    #endif

This will be helpful for separating out architecture-specific code blocks.
