glsl: Add built-in functions for GLSL 1.50.

This makes basic built-in functions work in GLSL 1.50.  It supports
everything except the new Geometry Shader functions.

The new 150.glsl file is 140.glsl plus ARB_texture_multisample.glsl;
150.frag is identical to 140.frag except for the #version bump.
