There is a demangler testsuite in libiberty and I added a few new
tests which are failed with the old demangler. The new demangler
passed all of them. I assume the outputs must be the same.

BTW, I am not sure when/if the new demangler will show up in mainline
libiberty. That is why I am putting it in my Linux binutils. People
can also apply it to their own gdb source to get a better demangler.
