## Message

```
stage2: merge MOV back with arith instructions

* turns out MOV and other arithmetic instructions such as ADD can
  naturally share the same lowering codepath (for the same variants)
* there are variants that are specific to ADD, or MOV which will be
  implemented as standalone MIR tags
* tweak Isel tests to generate corresponding test cases for all
  arithmetic instructions in comptime

```
