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.

Some hw queries need their sample memory locations to have certain
alignment.  At the moment that isn't an issue, since the only hw query
is occlusion, so all samples have the same size.  But when others are
added with different sample sizes, this starts to be a problem.
