Subject: glsl: Bail after reporting an error for non-constant const_in parameters.
X-Git-Tag: 062012170305~4896^2~29

glsl: Bail after reporting an error for non-constant const_in parameters.

Otherwise we continue and hit the "Illegal formal parameter mode"
assertion.

Fixes negative compile test texelFetchOffset.frag in piglit.
