Commit Message

Chinmay Rath May 23, 2024, 9:44 a.m. UTC 
Moving the following instructions to decodetree specification :

	v{add,sub}{u,s}{b,h,w}s		: VX-form

The changes were verified by validating that the tcg ops generated by those
instructions remain the same, which were captured with the '-d in_asm,op' flag.
