[LLVMdev] weird function

I don't know how hard it would be to compile the C++ standard library to
bitcode.  I've done this for Ada (which also has a substantial runtime
and standard library): compiling the runtime and standard libraries to
bitcode; then linking bitcode for some program with it, optimizing the
linked bitcode (LTO), and producing a final executable.

Ciao,

Duncan.
