Sorry for the delay. In general, if you keep the changes as simple
and disjoint as possible, I'm more likely to look at them soon :).
Here you could split up the "allow custom legalize of rotates" part
from the "introduce some temporary vars" part from "match ext rotate
cases" part.

Changes in directory llvm/lib/CodeGen/SelectionDAG:

LegalizeDAG.cpp updated: 1.485 -> 1.486
---
Log message:
1. Insert custom lowering hooks for ISD::ROTR and ISD::ROTL.
2. Help DAGCombiner recognize zero/sign/any-extended versions of ROTR and ROTL
patterns. This was motivated by the X86/rotate.ll testcase, which should now
generate code for other platforms (and soon-to-come platforms.) Rewrote code
slightly to make it easier to read.
