The `explicit_copy_value` and `explicit_copy_addr` instructions are only used for non-copyable diagnostics in the mandatory pipeline. After that we can replace them by their non-explicit counterparts so that optimizations (which only know of `copy_value` and `copy_addr`) can do their work. rdar://159039552
