PATCH: Support the new demangler written in C++

["H. J. Lu" <hjl at lucon dot org>]

I updated my demangler patch. I don't like the idea to have a second
<vector> when there is one in libstdc++ already. This patch makes all
but libstdc++ depend on demangler. I added 2 new targets to libiberty,
new_demangler and old_demangler, which are used by demangler. When
demangler is the part of gcc or src, it will do

	cd ...../libiberty && make [new_demangler|old_demangler]

depending if a working C++ compiler is available or not, and
libdemangler won't be installed. If the demangler directory doesn't
exist, libiberty will be the same as before. I believe this should
resolve most of the issues people have raised. Any comments?
