pan/mdg: Allow scheduling "x + x" to multipliers

One of the neat things with Midgard's wacky VLIW... on VADD/SADD this is
(x + x) literally, on VMUL/SMUL/VLUT this is (x * 2.0) where the 2.0 is
exactly representable in FP16 so it fits nicely as an inline constant.
So we don't need to restrict its scheduling.
