PR libstdc++/85222 allow catching iostream errors as gcc4-compatible ios::failure
Define a new exception type derived from std::ios::failure[abi:cxx11]
which also aggregates an object of the gcc4-compatible ios::failure
type. Make __throw_ios_failure throw this new type for iostream errors
that raise exceptions. Provide custom type info for the new type so that
it can be caught by handlers for the gcc4-compatible ios::failure type
as well as handlers for ios::failure[abi:cxx11] and its bases.
