Jakob Stoklund Olesen 46feaf86cf Handle register masks in LiveVariables. 
A register mask operand kills any live physreg that isn't preserved.
Unlike an implicit-def operand, the clobbered physregs are never live
afterwards.

This means LiveVariables has to track a much smaller number of live
physregs, and it should spend much less time in addRegisterDead().
