[AMDGPU] Regenerate codegen tests to check extra stuff at end of line (#187325) 
Regenerate checks after two recent commits that caused extra stuff to be
added at the end of assembly lines, so the existing checks did not fail.

- #179414 added "nv" to loads and stores on GFX1250.
- #185774 added "msbs" comments on setreg instructions.
