As mentioned in http://lists.llvm.org/pipermail/llvm-dev/2020-July/143395.html, loop-unswitch has not been ported to the NPM. Instead people are using simple-loop-unswitch. Pin all tests in Transforms/LoopUnswitch to legacy PM and replace all other uses of loop-unswitch with simple-loop-unswitch. One test that didn't fit into the above was 2014-06-21-congruent-constant.ll which seems to only pass with loop-unswitch. That is also pinned to legacy PM. Now all tests containing "-loop-unswitch" anywhere in the test succeed with NPM turned on by default. Reviewed By: ychen Differential Revision: https://reviews.llvm.org/D85360
