Subject: libstdc++: Move definition earlier in file

libstdc++: Move definition earlier in file

This moves __is_array_convertible so it's not between
__is_nothrow_convertible and its helper, since it isn't related to
those.

	* include/std/type_traits (__is_array_convertible): Move definition
	to immediately after is_convertible.
