  [3.4 regression] function-at-a-time generates stabs in bad order

This imparirs stabs+ support significantly.

Anonymous unions are another regression area.

I have "compare by gcc" tables but I haven't analyzed them yet.
This one bug causes so many problems that it's hard to look at
other stabs+ problems.

Grossly, there are about 27 new FAILS with gcc HEAD -gdwarf-2
versus gcc 3.3.2 -gdwarf-2, and about 28 new FAILS with gcc HEAD
-gstabs+ versus gcc 3.3.2 -gstabs+.
