put it in a new header System/Host.h instead.
Instead of getting the endianness from configure,
calculate it directly.

using the minimum possible number of bytes.  For little
endian targets run on little endian machines, apints are
stored in memory from LSB to MSB as before.  For big endian
targets on big endian machines they are stored from MSB to
LSB which wasn't always the case before (if the target and
host endianness doesn't match values are stored according
to the host's endianness).  Doing this requires knowing the
endianness of the host, which is determined when configuring -
thanks go to Anton for this.  Only having access to little
endian machines I was unable to properly test the big endian
part, which is also the most complicated...

--enable-expensive-checks allows the developer to enable runtime
checking that can greatly increase compile time.  Currently it only
turns on _GLIBCXX_DEBUG.  Other expensive debugging checks added later
should be controlled by this configure option.

This patch also updates llvm-config with a --cppflags option to inform
llvm-gcc how to build itself so that it is compatible with an llvm that
was built with _GLIBCXX_DEBUG.
