Log:
libstdc++: Fix some -Wsystem-headers warnings

	* include/bits/alloc_traits.h (allocator_traits::construct)
	(allocator_traits::destroy, allocator_traits::max_size): Add unused
	attributes to parameters that are not used in C++20.
	* include/std/bit (__ceil2): Add braces around assertion to avoid
	-Wmissing-braces warning.
