[Mesa-dev] [PATCH] glsl: fix compat shaders in GLSL 1.40

[Timothy Arceri]

The compatibility and core tokens were not added until GLSL 1.50,
for GLSL 1.40 just assume all shader built with a compat profile
are compat shaders.

Fixes rendering issues in Dawn of War II on radeonsi which has
enabled OpenGL 3.1 compat support.
