Re: [c++] Keep tm, div_t, ldiv_t, lconv mangling on Solaris (PR libstdc++-v3/1773)

There might be an alternative implementation that is less invasive to
the C++ frontend, though: add

&& TARGET_DECL_NAMESPACE_STD_P (decl)

in write_unscoped_name, defaulting to true, override it in sol2.h (which
gets included via tm.h) and have the remaining logic in a new sol2-cxx.c
file.

I would be OK with a target hook. I think a cleaner place would be to hook decl_mangling_context and then change write_unscoped_name to use decl_mangling_context instead of CP_DECL_CONTEXT.
