Fix failing tests.

This patch increases compile-time overall a bit (details in description). The impact could likely be even small if we only run LoopSimplifyCFG only on loops that indvars changed. This could be done by either exposing a simplifyLoopCFG helper function and use it in indvars or adding a way to mark loops for which LoopSimplifyCFG should run (similar in spirit to D115052 <https://reviews.llvm.org/D115052>).

I'm curious what people think :)
