PATCH for save_tree_status

[Mark Mitchell <mark at markmitchell dot com>]

The save_tree_status function mishandles the case where the context
of the new function is NULL, but we're at global scope.  It would be
useful to handle this case, so that we can use save_tree_status during
template instantiation in C++ front-end.  

This change has been bootstrapped/checked on x86-linux-gnu.

Would someone care to approve this patch?

Thanks,

	as nested.
