Add dag combiner code to recognize rotl, rotr
Add ppc code to match rotl

Targets should add rotl/rotr patterns if they have them

pointer.  This allows us to emit stuff like this:

        li r10, 0
        stw r10, 56(r1)
        or r3, r10, r10
        or r4, r10, r10
        or r5, r10, r10
        or r6, r10, r10
        or r7, r10, r10
        or r8, r10, r10
        or r9, r10, r10
        bl L_bar$stub

instead of this:

        or r2, r1, r1     ;; Extraneous copy.
        li r10, 0
        stw r10, 56(r2)
        or r3, r10, r10
        or r4, r10, r10
        or r5, r10, r10
        or r6, r10, r10
        or r7, r10, r10
        or r8, r10, r10
        or r9, r10, r10
        bl L_bar$stub

* ExternalSymbol -> TargetExternalSymbol as direct function callee.
* Use X86::ESP register rather than CopyFromReg(X86::ESP) as stack ptr for
