[PATCH] D38631: [SimplifyCFG] use pass options and remove the latesimplifycfg pass

[Sanjay Patel via Phabricator via llvm-commits]

Patch updated:

1. We have another option intended to limit simplifycfg around switches early in the pipeline with https://reviews.llvm.org/rL316298.
2. Fixed the new pass manager code to continue to create latesimplifycfg-equivalent passes because this patch is NFCI. I created a phase ordering test for both PMs (it's based on the example from https://reviews.llvm.org/D35411) to show the bug and added it with https://reviews.llvm.org/rL316351.
