UnitTests: Fix warnings from HermesText

Most of these correspond to changes made in devkitPro/libogc@b1b8ecab3a.

The numeric vlaues of ACC0 and ACC1 in Dolphin are different (see b06d38389b, though I'm not sure when this difference first appeared). Technically it's not even necessary to list the registers at the start like this anymore, but old programs do it, so it seems useful to have a test that covers it.

The binary itself does not need to be changed; the warnings were simply stating that "although you wrote $ACL0, the generated binary instead is using $ACC0" or similar; by changing the code to use $ACC0 directly the warnings are resolved.
