libstdc++ baseline updates for 3.4/HEAD

[B. Kosnik]

Matthias,

I'm working on getting access to additional arches.

This difference still puzzles me, however.

%as --version
GNU assembler 2.15.90 20040401

%ld --version
GNU ld version 2.15.90 20040401

Ok

Yes

No! This is the part that puzzles me. These are explicitly instantiated
in io-inst.o: you should see weak symbols in that object file.

%objdump -t io-inst.o | grep _ZNSdC2Ev
00000000 l    d  .gnu.linkonce.t._ZNSdC2Ev      00000000
00000000  w    F .gnu.linkonce.t._ZNSdC2Ev      00000045 _ZNSdC2Ev

%c++filt _ZNSdD1Ev
std::basic_iostream<char, std::char_traits<char> >::~basic_iostream()
