Bjorn Pettersson 951a980dc7 [Analysis] Make order of analysis executions more stable ...

When debugging and using debug-pass-manager (e.g. in regression tests)
we prefer a consistent order in which analysis passes are executed.
But when for example doing

  return MyClass(AM.getResult<LoopAnalysis>(F),
                 AM.getResult<DominatorTreeAnalysis>(F));

then the order in which LoopAnalysis and DominatorTreeAnalysis isn't
guaranteed, and might for example depend on which compiler that is
used when building LLVM.

I've not scanned the full source tree, but this fixes some occurances
of the above pattern found in lib/Analysis.

This problem was discussed briefly in review for D146206.
