vkd3d-shader/hlsl: Make pre/post decrement generate a signed one.

Browse Source 
If a float expression is pre/post decremented and an unsigned one is
used to execute it, the unsigned one is first negated (becoming 2^32-1)
and then casted to float (becoming 2^32), which leads to an incorrect
result.
