    compiler/glsl: Fix uniform location counting.

    This patch moves the calculation of current uniforms to
    link_uniforms, which makes use of UniformRemapTable which
    stores all the reserved uniform locations.

    Location assignment for implicit uniforms now tries to use
    any gaps left in the table after the location assignment
    for explicit uniforms. This gives us more space to store more
    uniforms.

    Patch is based on earlier patch with following changes/additions:

       1: Move the counting of explicit locations to
          check_explicit_uniform_locations and then pass
          the number to link_assign_uniform_locations.
       2: Count the number of empty slots in UniformRemapTable
          and store them in a list_head.
       3: Try to find an empty slot for implicit locations from
          the list, if that fails resize UniformRemapTable.

    Fixes following CTS tests:
