LoopRotate: canonicalize Struct BB args after UpdateSSA.

Without this, IndvarAnalysis can spuriously fail.

Roughly:
%i0 = integer_literal
%s0 = struct %i0
br (%i0, %s0)

bb(%i1, %s1)

Becomes:
%i0 = integer_literal
br (%i0)

bb(%i1)
%s0 = struct %i1

Add a SILSSAUpdate utility

This is using LLVM's SSAUpdater utility.

I had to abstract it a little further because our 'phi' nodes are slightly
different. The SSAUpdater needs to iterate over phis in a basic block so I
abstracted this in a trait. Therefore, this commit needs a recent version of
puzzle/master which has this change applied.
