Some MAX_* constants, like GL_MAX_VERTEX_UNIFORM_COMPONENTS, are
available to the [require] section. Since MAX_*_ATOMIC_COUNTERS can be
zero, we should probably support for it.
Looking at the way the GL_MAX_* checks are structured in
shader_runner.c, it could probably use a refactor to a table-based approach.
