Fix PR2748. Avoid coalescing physical register with virtual register which would create illegal extract_subreg. e.g.
vr1024 = extract_subreg vr1025, 1
...
vr1024 = mov8rr AH
If vr1024 is coalesced with AH, the extract_subreg is now illegal since AH does not have a super-reg whose sub-register 1 is AH.

Fix a bug in the coalescer where it didn't check if a live interval existed before trying to manipulate it.  This
was exposed by fast isel's handling of shifts on X86-64.  With this, FreeBench/pcompress2 passes on X86-64 in fast isel.
