This adds missing includes to internal library headers which get included from more than one other header, so that they can be compiled as a stand-alone header unit. For existing use cases these includes are no-ops because they're already done by the header that includes these files. For compiling them as a header unit, this ensures that they include what they use. libstdc++-v3/ChangeLog: PR libstdc++/99413 * include/bits/align.h: Include debug/assertions.h. * include/bits/codecvt.h: Include bits/c++config.h. * include/bits/enable_special_members.h: Likewise. * include/bits/erase_if.h: Likewise. * include/bits/functional_hash.h: Include <type_traits>. * include/bits/invoke.h: Include bits/move.h. * include/bits/ostream_insert.h: Include bits/exception_defines.h. * include/bits/parse_numbers.h: Include <type_traits>. * include/bits/predefined_ops.h: Include bits/c++config.h. * include/bits/range_access.h: Include bits/stl_iterator.h. * include/bits/stl_bvector.h: Do not include bits/stl_vector.h. * include/bits/stl_iterator.h: Include bits/stl_iterator_base_types.h. * include/bits/stl_uninitialized.h: Include bits/stl_algobase.h. * include/bits/uniform_int_dist.h: Include bits/concept_check.h. * include/bits/unique_lock.h: Include bits/std_mutex.h. * include/debug/assertions.h: Include bits/c++config.h.
