[PATCH] libiberty: fix URL for demangler ABI

[David Malcolm]

The comment at the top of cp-demangle.c lists:
  http://www.codesourcery.com/cxx-abi/abi.html#mangling
which redirects to:
  https://mentorembedded.github.io/cxx-abi/abi.html#mangling
but this is a 404: the latter site is empty.

I looked on archive.org; the final version before the redirect
seems to be:
  https://web.archive.org/web/20110903075217/http://www.codesourcery.com:80/public/cxx-abi/abi.html

Some searching showed up:
  https://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling

I don't know how canonical this page is, but:
  https://itanium-cxx-abi.github.io/cxx-abi/
has "Revised March 14, 2017", which seems relatively up-to-date, so this
patch updates the comment to point to that site.

OK for trunk?

 /* This code implements a demangler for the g++ V3 ABI.  The ABI is
    described on this web page:
-       http://www.codesourcery.com/cxx-abi/abi.html#mangling
+       https://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling
 
    This code was written while looking at the demangler written by
    Alex Samuel <samuel@codesourcery.com>.
