[wwwdocs,libstdc++] Remove libstdc++/

[Gerald Pfeifer <gerald at pfeifer dot com>]

Our libstdc++/ page dates back to when libstdc++ was merged into GCC in 
2000, 0x10 years ago.  It has been a mostly empty shell for most of that 
time period and hardly seen any updates in the last decade.

So, after https://gcc.gnu.org/ml/gcc-patches/2016-08/msg01467.html I 
suggest to streamline things, remove this page, and apply the patch
below.

Any big concerns or fierce objections?

Gerald

-<p>The GNU Standard C++ Library v3, or libstdc++-v3.  Older snapshots of

-<h2>What... is your quest?</h2>
-
-<p>This is an ongoing project to implement the ISO 14882 Standard

-<h3><a name="download">Downloading</a></h3>
-
-<p>libstdc++-v3 is developed and released as part of GCC, separate
-   snapshots are no longer made available.  The libstdc++-v3 sources are
-   included with the GCC sources and can be downloaded from the GCC FTP
-   area or from any of the <a href="../mirrors.html">GCC mirror sites</a>.
-</p>
-
-<p>The SVN source repository is part of the GCC repository.  Instructions
-   for anonymous SVN access are the same as
-   <a href="../svn.html">those for the rest of the compiler</a>.  Checking
-   out the GCC <code>trunk</code> or one of the branches will also get the
-   library sources; to retrieve only the library, check out
-   <code>trunk/libstdc++-v3</code> instead.
