The stack needs to be able to take indexing without changing the stack pointer so we're using a std::vector for that.  The std::string section would be a lot easier to replace than the two I just mentioned since we store the length separately.

If you really want to stick with std::string and std::vector, I'd
suggest just writing some wrappers for the relevant functions.  For
example:

extern "C" char* String_cstr(std::string*);
extern "C" void Stack_pushback(std::vector*, void* value);

You can even compile these to bitcode with llvm-g++ and inline them
into your other IR.

I don't think compiling libstdc++ to bitcode actually helps you here;
you can call the relevant functions in libstdc++ whether or not
they're bitcode.
