stdexcept missing when compiling in 32-bit mode with clang-trunk

[pps83]

stdexcept can be included when compiling using clang-trunk, however, when you use -m32 to compile in 32-bit mode stdexcept becomes missing and the error output is:

#include <stdexcept>
         ^~~~~~~~~~~
1 error generated.
Compiler returned: 1```

Per #431, you need -stdlib=libc++. (If you need to use libstdc++, --gcc-toolchain=/opt/compiler-explorer/gcc-snapshot seems to do the trick.)

Seems to have become fixed along the way.
