Some required extension might be missing, and we may expose a GLSL
version that does not match up with the GL version. Fix that up when
computing the GL version.

This looks OK, but another approach might be to have a new function which
returns the GLSL version for a given GL version (could be encoded in a small
table).  Then, use that function to clamp/set consts->GLSLVersion.  That way
we can keep the nice const-ness of the compute_version() parameters.

Where do you envision the clamping be done?

How about _mesa_compute_version()?
