is a qualified union type, so not all fields are always

LLVM type being larger than the gcc TYPE_SIZE.

Make MachineRegisterInfo::getVRegDef more efficient by aiming the keep the def of the vreg at the start of the list, so the list doesn't need to be traversed.

Add a new MachineRegisterInfo::replaceRegWith, which is basically like
Value::replaceAllUsesWith.

Fix a bug in my previous patch: refer to the impl not the pure virtual version.  It's unclear why gcc would ever compile this...
