- Fixed miscompilation with Clang 3.5.0.

Browse source 
The optimizer miscompiles the function FBehavior::LoadScriptsDirectory and causes random crashes when zdoom is run with wads containing scripts.
As said in the comment, I just hope that the Clang devs fix it for the next patching release, ie 3.5.1.
