NIR ALU operations:
* nir_op_fabs
* nir_op_iabs
* nir_op_fneg
* nir_op_ineg
* nir_op_fsat
should be lowered by lower_source mods
* nir_op_fdiv
should be lowered in the compiler by DIV_TO_MUL_RCP.
* nir_op_fmod
should be lowered in the compiler by MOD_TO_FLOOR.
* nir_op_fsub
* nir_op_isub
should be handled by ir_sub_to_add_neg.
