We don't actually combine a hard reg with a pseudo; instead
we just record the hard reg as the suggestion for the pseudo's quantity.
If we really combined them, we could lose if the pseudo lives
- across an insn that clobbers the hard reg (eg, movstr).
+ across an insn that clobbers the hard reg (eg, movmem).
ALREADY_DEAD is nonzero if USEDREG is known to be dead even though
there is no REG_DEAD note on INSN. This occurs during the processing
