Fix bug in RegScavenger::scavengeRegister().
Reserved registers are not candidates for scavenging, and they were removed
from the candidate list like this:
CreateRegClassMask(RC, Candidates);
Candidates ^= ReservedRegs;
However, when there are reserved registers outside RC, this causes invalid
bits to be set in Candidates.
