[StructurizeCFG] Correctly depend on UniformityAnalysis

Small oversight in https://reviews.llvm.org/D145688 - the pass' dependency was not updated to reflect the change to UA.

Also, change DivergenceAnalysis to UniformityAnalysis in a comment. That way, StructurizeCFG only refers to UA and not DA anymore.
