isOperandLegal mostly implemented the VALU operand rules, and largely ignored SALU restrictions. This theoretically avoids folding literals into SALU insts which already have a literal operand. This issue is currently avoided due to a bug in SIFoldOperands; this change will allow using raw operand legality rules. This breaks the formation of s_fmaak_f32 in SIFoldOperands, but it probably should not have been forming there in the first place. TwoAddressInsts or RA should generally handle that, and this only worked by accident.
