Jakob Stoklund Olesen b83a6b23dc Teach TargetRegisterInfo how to cram stack slot indexes in with the virtual and ...

physical register numbers.

This makes the hack used in LiveInterval official, and lets LiveInterval be
oblivious of stack slots.

The isPhysicalRegister() and isVirtualRegister() predicates don't know about
this, so when a variable may contain a stack slot, isStackSlot() should always
be tested first.
