Jakob Stoklund Olesen 56fe2ed51e Handle register mask operands in setPhysRegsDeadExcept(). ...

Calls that use register mask operands don't have implicit defs for
returned values.  The register mask operand handles the call clobber,
but it always behaves like a set of dead defs.

Add live implicit defs for any implicitly defined physregs that are
actually used.
