libstdc++: Do not cast away const-ness in std::construct_at (LWG 3870)
This change also requires implementing the proposed resolution of LWG
3216 so that std::make_shared and std::allocate_shared still work, and
the proposed resolution of LWG 3891 so that std::expected still works.
libstdc++-v3/ChangeLog:
* include/bits/shared_ptr_base.h: Remove cv-qualifiers from
type managed by _Sp_counted_ptr_inplace, as per LWG 3210.
* include/bits/stl_construct.h: Do not cast away cv-qualifiers
when passing pointer to placement new.
* include/std/expected: Use remove_cv_t for union member, as per
LWG 3891.
* testsuite/20_util/allocator/void.cc: Do not test construction
via const pointer.
