Use computeOverflowForUnsignedAdd and DAG.computeOverflowForSignedAdd
instead. Unfortunately, this recomputes some known bits and sign bits
we may have already computed, but was the easiest fix without a lot
of restructuring.

This recovers the regressions from D151472 <https://reviews.llvm.org/D151472>.
