[Bug pch/13676] New: GCC failes to recognize files ending in .hpp as headers to be precompiled

["jbrandmeyer at earthlink dot net" <gcc-bugzilla at gcc dot gnu dot org>]

Pass any header file with a suffix ending in .hpp to the compiler.  If -c is
specified, you recieve the message that "linker input file foo.hpp ignored
because linking not done", and if -c is not specified, it is passed on verbatim
to the linker which cannot subsequently determine the file type.

I think the most robust fix for this is to supply an argument to the -x flag
such as "c++-pch" or "c-pch" to force the compiler to treat it as a header file
to be pre-compiled.  This would also enable projects that do more exotic things
with #include to take advantage of PCH.
