7684d57a05 nir: add a pass to optimize "gl_FragDepth = gl_FragCoord.z" away 
gl_FragDepth default value is gl_FragCoord.z so if a shader does:

   gl_FragDepth = gl_FragCoord.z

we can drop this assignment.

v2: use nir_ssa_scalar_resolved and don't do this is gl_FragDepth
    is wrote multiple times (Jason)
v3: - move to its own pass (Jason)
    - handle var = NULL (Rhys)
v4: refactoring (Jason)
