a1fbf3459f Exceptions store the message as reference counted string for
compatibility to libstdc++. Move the implementation into a header for
easier sharing with libc++abi. Merge a number of improvements from that
version. Provide a POD definition for <stdexcept>'s public use to avoid
cast dances. Discussed with Marshall Clow.

0b438a9f63 Build fix for gcc builtin
The __sync_add_and_fetch() builtin parameter is volatile but clang has
'different' type checking and ends up accepting this code.

Undo the C++ cast from r198505 to get libc++/LLVM building with g++ while this
is investigated.

70d4ba7f19 Replace casts of __impl_ with the correct reinterpret_cast of the
address. Restores the assembly of before r198504.

26dd09e57f Make it possible to link against libstdc++ as well as libsupc++ with CMake.
Linking against libstdc++, rather than libsupc++, is probably better
for people who need to link against clients of libstdc++.  Because
libsupc++ is provided only as a static library, its globals are not
shared between the static library and the copy linked into libstdc++.
This has been found to cause at least one test failure.

This also removes a number of symbols which were multiply defined
between libstdc++ and libc++, only when linking with libstdc++.

27841fd803 Matthew Dempsky: Same as stdexcept.cpp in libc++abi: we've already computed 'len strlen(msg)', so we can use memcpy() instead of strcpy().

d79842c2bf Change size of reference count field in __libcpp_nmstr from 32 bits to 64 bits for 64 bit targets. This is controls the data layout of all exceptions defined in <stdexcept>. This aligns the ABI with that of gcc-4.2.

11ffde3d7e libc++: only #include <cxxabi.h> if it exists. This allows libc++ to build
out of the box on Linux systems. If you're building against libc++abi, you
still need to make sure it can find <cxxabi.h> so it knows not to export
symbols which libc++abi provides.

128ba7191d patch by Jeffrey Yasskin for porting to Ubuntu Hardy. Everything was accepted except there were some bug fixes needed in <locale> for the __nolocale_* series. For the apple branch I ended up using templates instead of the var_args solution because it seemed both safer and more efficient.
