[SimplifyCFG] Handle branch on same condition in pred more directly

Rather than creating a PHI node and then using the PHI threading
code, directly handle this case in
FoldCondBranchOnValueKnownInPredecessor().

This change is supposed to be NFC-ish, but may cause changes due
to different transform order.
