Chris Lattner 37944985a5 Fix a bug in the scheduler's handling of "unspillable" vregs.

Imagine we see:

EFLAGS = inst1
EFLAGS = inst2 FLAGS
gpr = inst3 EFLAGS

Previously, we would refuse to schedule inst2 because it clobbers
the EFLAGS of the predecessor.  However, it also uses the EFLAGS
of the predecessor, so it is safe to emit.  SDep edges ensure that
the right order happens already anyway.

This fixes 2 testsuite crashes with the X86 patch I'm going to
commit next.
