Re: [Dpcl-develop] DPCL on x86-64

Assuming Dyninst uses __x86_64, use that. The only other define that looks 
like it makes sense is __x86_64__, and I don't see any other reason for 
choosing one over the other except for what the Dyninst code uses now.

This should be used only for changes specific to the processor's 
instruction set, as was done with lock.c for ia64. Anything that is a 64 
bit specific change unrelated to  implementing support for this specific 
processor should still use the __64_BIT define unless we find problems 
with that.
