Don't assume it's safe to transform a loop just because it's dominated by any
comparison. Fixes bug 1598.

Treeadd has a for loop from 0 to 100 that scalar-evolution isn't able to
determine the bounds of. Attached is a patch that handles the unusual
case where the exit branch indirectly leads back to the loop header.
It didn't cause any miscompiles in llvm-test (excl. External) and I did
a count of how

Predicate simplifier uses this to get the DFS nums for a BB. We also
pass around ETNode*s to avoid having a lot of functions doing BB->ETNode
lookups.
Similarly with updateDFSNumbers. More than a performance issue, if the
DFS nums aren't up to date predsimplify will crash (and if it didn't
crash i
