Matthias Braun 5b7c90b4e2 RegAllocFast: Leave unassigned virtreg entries in map

Set `LiveReg::PhysReg` to zero when freeing a register instead of
removing it from the entry from `LiveRegMap`. This way no iterators get
invalidated and we can avoid passing around and updating iterators all
over the place.

This does not change any allocator decisions. It is not completely NFC
because the arbitrary iteration order through `LiveRegMap` in
`spillAll()` changes so we may get a different order in those spill
sequences (the amount of spills does not change).

This is in preparation of https://reviews.llvm.org/D52010.
