Don't change type of input and output var in dead member elim (#2412)
The types of input and output variables must match for the pipeline.  We
cannot see the uses in all of the shader, so dead member
elimination cannot safely change the type of input and output variables.

Add pass to remove dead members. (#2379)
Add a pass that looks for members of structs whose values do not affects
the output of the shader. Those members are then removed and just
treated like padding in the struct.
