Subject: [PATCH] Fix state flag dependencies for fixed function fragment
 program updates.

I started looking into why _NEW_ARRAY punishes us, and while annotating
dependencies noticed that a bunch of dependencies were missing.

(cherry picked from master, commit e5f63c403b767f9974e8eb5d412c012b8a69287f)
