[LLVMdev] LLVM API: how to determine if the register is the status register

Why do you need this and what you're trying to do? There is no "status
register"
stuff inside LLVM, so there is no way to query for it. Also, reg
numbers exist only
inside particular target backend, thus you can always just compare
with target-specific reg.
