9a6b92de4c Remove integer promotion support for FP_EXTEND
and FP_ROUND.  Not sure what these were doing
here - probably they were sometimes (wrongly)
created with integer operands somewhere that
has since been fixed.

331a746101 LegalizeTypes support for splitting and scalarizing

once llc gets past scalar-to-vector it hits a SPU target
lowering bug and explodes.

2d093f3560 Avoid using a loop in ReleasePred and ReleaseSucc methods to compute the
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.

the scheduler arbitrary decision differently.

1e465a35c8 Simplify SplitVecRes_EXTRACT_SUBVECTOR. This means
that it no longer handles non-power-of-two vectors.
However it previously only handled them sometimes,
depending on obscure numerical relationships between
the index and vector type.  For example, for a vector
of length 6, it would succeed if and only if the
index was an even multiple of 6.  I consider this
more confusing than useful.
