linker: Split set_uniform_binding into separate functions for blocks and samplers

The two code paths are quite different, and there are some problems in
the handling of uniform blocks.  Future changes will cause these paths
to diverge further.  Ultimately, selecting between the two functions
will happen at the set_uniform_binding call site, and
set_uniform_binding will be deleted.

NOTE: This patch just moves code around.
