This only converts the instances where all that is needed is to change
the variable type name.

Basically, anything that involves a function that LiveRegUnits does not
directly have was skipped to play it safe.

This reverts commit 2a13422b8bcee449405e3ebff957b4020805f91c.

It was causing test failures on the expensive check builders.

This function did a check which was broken to see if an opcode requires op0
and op1 to be tied. By chance this is NFC.

possible in SystemZShortenInst.
