[LLVMdev] Making a CopyToReg/CopyFromReg into a zext/sext?

I have a CopyToReg that is copying from different size types, what's the
best way to change that to a zext or sext node based on signed or unsigned?
I'm fairly unfamiliar with SelectionDAG process (outside of the docs on
llvm website).
It seems like I should be able to insert a custom hook using the register
class to identify the type, potentially in ISelDAGToDag.cpp or is there a
better place for this to be done?
Thanks.
