Building on D152659 <https://reviews.llvm.org/D152659>, fold add/mul with their neutral elements.

There is a large number of tests that need updating, which I will do
if/once there's agreement on the direction. The missing fold was pointed
out in D147783 <https://reviews.llvm.org/D147783>

Depends on D152659 <https://reviews.llvm.org/D152659>.
