here - probably they were sometimes (wrongly)
created with integer operands somewhere that
has since been fixed.

Fix a bug introduced by my previous patch.  With this change, SPEC is now clean with prealloc splitting enabled.

SCALAR_TO_VECTOR.  I didn't add the testcase, because
once llc gets past scalar-to-vector it hits a SPU target
lowering bug and explodes.

Use it to safely handle less-than-or-equals-to exit conditions in loops. These
also occur when the loop exit branch is exit on true because SCEV inverses the
icmp predicate.

Use it again to handle non-zero strides, but only with an unsigned comparison
in the exit condition.

new CycleBound value. Instead, just update CycleBound on each call.
Also, make ReleasePred and ReleaseSucc methods more consistent accross
the various schedulers.

This also happens to make ScheduleDAGRRList's CycleBound computation
somewhat more interesting, though it still doesn't have any noticeable
effect, because no current targets that use the register-pressure
reduction scheduler provide pipeline models.
