Evan Cheng d29fc6655f If there is a def of a super-register followed by a use of a sub-register, do *not* add an implicit def of the sub-register. e.g. ...

EAX = ..., AX<imp-def>
...
    = AX

This creates a double-def. Apparently this used to be necessary but is no longer needed.

Thanks to Anton for pointing this out. Anton, I cannot create a test case without your uncommitted ARM patches. Please check in a test case for me.
