Add passes to eliminate dead output stores (#4970) 
This adds two passes to accomplish this: one pass to analyze a shader
to determine the input slots that are live. The second pass is run on
the preceding shader to eliminate any stores to output slots that are
not consumed by the following shader.

These passes support vert, tesc, tese, geom, and frag shaders.

These passes are currently only available through the API.

These passes together with dead code elimination, and elimination of
dead input and output components and variables (WIP), will allow users
to do dead code elimination across shader boundaries.
