[Mesa-dev] [PATCH] glsl: Rename linker's is_varying_var

[Chris Forbes]

Both the ast->IR and linker have functions with this name, but different
behavior.

Rename the linker's version to var_counts_against_varying_limit to be
closer to what it is actually used for.

Suggested by Ian a while back.

Note that there's actually a bug lurking in here -- check_against_output_limit won't actually count anything, since it requires var->data.mode == ir_var_shader_out and stage != MESA_SHADER_FRAGMENT.
