Subject: [PATCH] libstdc++: Add <initializer_list> to ranges_base.h header

The header should be included explicitly to use std::initializer_list.
With the upcoming changes to make <ranges> available for freestanding
this becomes an error, because <initializer_list> is no longer provided
by any of the other headers involved here.

libstdc++-v3/ChangeLog:

	* include/bits/ranges_base.h: Include <initializer_list>.
