Serguei Katkov 529f42331e [SCEV] Re-land: Fix isKnownPredicate
This is re-land of https://reviews.llvm.org/rL327362 with a fix
and regression test.

The crash was due to it is possible that for found MDL loop,
LHS or RHS may contain an invariant unknown SCEV which
does not dominate the MDL. Please see regression
test for an example.
