aco: disable mul(cndmask(0, 1, b), a) optimization sometimes

This optimization doesn't work for SDWA or DPP multiplications and we
can't do it if denormal flushing is required because v_cndmask_b32 doesn't
do that and we can't do it if we can't assume operands are finite because
0.0 * inf is NaN, not 0.
