| Checks for li support |

| This is really a test of the assembler, which is supposed to expand the li |
| pseudo-instruction into addi/lui as necessary. Of course, checking that the |
| expansion was correct is a little difficult, unless you can run the |
| generated instructions... which is what we can do for ISS testing. So the |
| checks seem to fit quite well here. |
