97ecb83dff More domain conversion; convert VFP VMOVS to NEON instructions in more cases - when we may clobber the other S-lane by converting an S to a D instruction, make an effort to work out if the S lane is clobberable or not.

7bebddf55e Strip old MachineInstrs *after* we know we can put them back. 
Previous patch accidentally decided it couldn't convert a VFP to a
NEON instruction after it had already destroyed the old one. Not a
good move.
