Introduce C++ support in libcc1

Extend libcc1's with an API for C++ support.

Extend libcc1's C API to distinguish between integral types with the
same width, as in C++.  Likewise for float types.

Export small bits of functionality from the C++ front-end for use in
libcc1.  Add support for the C++ front-end to look up names and
addresses using a libcc1-registered binding oracle.  Add support for
global friends.
