FYI: A new C++ demangler

[Michael Elizabeth Chastain]

I will throw the new demangler on my gdb test bed and look for regressions.
I'm sure H. J. has the demangler test suite covered and I can do the
gdb test suite.

I have kind of a silly question.  Do I need to rebuild binutils and/or gcc
with the new demangler, or can I just rebuild gdb?  That is, do gcc or
binutils ever need to run the demangler while compiling?

Regarding the controversy about adding a demangler written in C++,
I am neutral about that.  I'll just provide gdb test results.
