[LLVMdev] llvm::Triple support for haswell-enabled x86_64

[Zachary Turner]

Sounds good, I'll give it a try sooner or later.  I've never messed with
triples, so is there anything I need to be aware of so I don't break any
code on other platforms?  In particular, I want
llvm::sys::getDefaultTargetTriple() to return me this new haswell-aware
triple, so what do I need to do to ensure that I don't break anyone else
who is running one of these systems and previously had a different default
triple?
