Add narrowWideReferences to .graph files

Generate narrowWideReferences as part of the compiler performance graphs (the

Swap order of LICM in .graph files

LICM was moved to run before prune2 a while back, I updated the .dat and
.perfkey order, but never changed it in the .graph files. The order doesn't
really matter but it's nice to have it in the same order that the passes run.
