Matthias Braun 9912bb817c MachineRegisterInfo: Remove UsedPhysReg infrastructure 
We have a detailed def/use lists for every physical register in
MachineRegisterInfo anyway, so there is little use in maintaining an
additional bitset of which ones are used.

Removing it frees us from extra book keeping. This simplifies
VirtRegMap.
