b668b6439a
Two changes in this patch: 1. Covered another case in legalizeOperandVALUt16 functions and the COPY lowering, when SALU16 is used by SALU32, need to insert a reg_sequence after moved to valu (previously only considered SALU32 used by SALU16 case) 2. Moved the useMI analysis into addUsersToMoveVALUList. Legalize the targetted operand when needed. Turn on frem test with true16 mode for gfx1150 which is failing before this patch. A few bitcast tests also impacted by this change with some v_mov being replaced to dual mov
