Serguei Katkov ee51ad3ba8 [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.
