[Mesa-stable] [PATCH v2] glsl: fix names in lower_constant_arrays_to_uniforms

Patch changes lowering pass to use unique name for each uniform
so that arrays from different stages cannot end up having same
name.

v2: instead of global counter, use pointer to achieve
    unique name (Kenneth Graunke)
