libstdc++: Fix -Wsystem-headers warnings
Fix some problems noticed with -Wsystem-headers.
libstdc++-v3/ChangeLog:
* include/bits/stl_tempbuf.h (_Temporary_buffer): Disable
warnings about get_temporary_buffer being deprecated.
* include/ext/functional (mem_fun1, mem_fun1_ref): Disable
warnings about mem_fun1_t, const_mem_fun1_t, mem_fun1_ref_t and
const_mem_fun1_ref_t being deprecated.
* include/std/array (__array_traits<T, 0>): Remove artificial
attributes which give warnings about being ignored.
* include/std/spanstream (basic_spanbuf::setbuf): Add assertion
and adjust to avoid narrowing warning.
* libsupc++/exception_ptr.h [!__cpp_rtti && !__cpp_exceptions]
(make_exception_ptr): Add missing inline specifier.
