Sometimes llvm-mc can generate more than one line of output from assembling a single instruction. It would be nice if `update_mc_test_checks` supported that properly.
Currently after `utils/update_mc_test_checks.py test/MC/AMDGPU/reloc-operands-gfx10.s` I see:
```diff

```
This does not work because it has put the two lines of output into a single CHECK line.
