LoopUnroll: Create sub-loops in LoopInfo
`LoopUnrollPass` says that it preserves `LoopInfo` -- make it so. In
particular, tell `LoopInfo` about copies of inner loops when unrolling
the outer loop.
Conservatively, also tell `ScalarEvolution` to forget about the original
versions of these loops, since their inputs may have changed.
Fixes PR20987.
