This is a more concentrated version of D85802 <https://reviews.llvm.org/D85802> which added a flag for
selecting between any C++ ABI at compile-time. This limits it down to
only explicitly using the Fuchsia C++ ABI as per the discussion at the
end of that review.

      

This will be used as a way to integrate code built with Clang with code
built by other compilers that don't contain Fuchsia-specific ABI
changes. The immediate use case is for generating multilibs that use the
generic Itanium ABI to be used by code built by GCC.
