AMDGPU: Teach isOperandLegal about SALU literal restrictions (#127626)
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.
