Apply -mregparm-style register parameter attributes to a function.
Declared in <llvm/Transforms/Utils/BuildLibCalls.h>
void
markRegisterParameterAttributes(Function* F);Handle -mregparm for the given function. Note that this function is a rough approximation that only works for simple function signatures; it does not apply other relevant attributes for function signatures, including sign/zero-extension for arguments and return values.
