From: Rob Clark <robcl...@freedesktop.org>
Split standalone glsl_compiler into a libstandalone.la and a thin
main.cpp. This way drivers can re-use the glsl standalone frontend in
their own standalone compilers.

There is one kinda ugly hack (#including a .cpp file) to work around
an automake issue.. not sure if there is a better way to do that, or
if we should bother caring (since it isn't something that is installed
anyways)
