gallium/auxiliary: add inc and dec alternative with return (v4)
At this moment we use only zero or positive values.
v2: Implement it for also for Solaris, MSVC assembly
and enable for other combinations.
v3: Replace MSVC assembly by assert + warning during compilation
v4: remove inc and dec with return for MSVC assembly
