Fix yet more problems to do with confusion over live range
definitions.  This commit gets rid of rev 180, which was wrong, and
rev 317, which was a kludge to try and cover 180's wrongness.

The correct solution is to compute live ranges correctly in the first
place.  In particular, if an insn #i reads a reg and that's the end of
the live range, we must say that insn's dead-before value is i+1 and
not i.
