From: Nicolai Hähnle <nicolai.haeh...@amd.com>
In order to be able to emit overlapping input and output array
declarations, we flip the logic of emitting those declarations on its
head: rather than iterating over slots and emitting the corresponding
declarations, we iterate over the declarations from GLSL and emit those.
