[Mesa-dev] [PATCH 1/2] compiler: Free types in _mesa_glsl_release_types() rather than autofree.

[Kenneth Graunke]

Instead of using ralloc_autofree_context() to install an atexit()
handler to ralloc_free(glsl_type::mem_ctx), we can simply free them
from _mesa_glsl_release_types().

This is effectively the same, because _mesa_glsl_release_types() is
called from _mesa_destroy_shader_compiler(), which is called from Mesa's
one_time_fini() function, which Mesa installs as an atexit() handler.

The one advantage here is that it ensures the built-in functions are
destroyed before the types.
