[LLVMdev] RFC: Atomics.h

[Owen Anderson]

OK, I've enhanced Atomic.h by pulling in a bunch of implementations  
from libatomic_ops, and others that I could figure out on my own.

Again, my plea: PLEASE TRY THIS OUT ON YOUR PLATFORM, AND SEND ME  
PATCHES IF IT DOESN'T WORK!  Similarly, if you think the  
implementation could be improved for your platform, send me a patch.

I know that Sparc doesn't work currently (no CAS implementation yet),  
and I'm a little unsure about the ARM version, so it'd be great if  
gurus for those platforms could look at them.
