[Mesa-dev] [PATCH 3/4] glsl: Remove unused function import_prototypes

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

Once upon a time, this was used to extract prototypes from the shader
containing GLSL built-in functions.  This was removed by f5692f45 in
November 2010 for Mesa 7.10.
