  Log Message:
  -----------
  Fix deletion of operations through the rewriter in a pattern matching a consumer operation

This allows for the conversion to match `A(B()) -> C()` with a pattern matching
`A` and marking `B` for deletion.

Also add better assertions when an operation is erased while still having uses.
