nir: split SSBO min/max atomic instrinsics into signed/unsigned versions

Browse Source 
NIR is typeless so this is the only way to keep track of the
type to select the proper atomic to use.

v2:
  - Use imin,imax,umin,umax for the intrinsic names (Connor Abbott)
  - Change message for unreachable paths (Michael Schellenberger)
