PR libstdc++/85951 for make_signed/make_unsigned for character types
...
Because the wide character types are neither signed integer types nor
unsigned integer types they need to be transformed to an integral type
of the correct size and the lowest rank (which is not necessarily the
underlying type). Reuse the helpers for enumeration types to select the
correct integer.
The refactoring of __make_unsigned_selector and __make_signed_selector
slightly reduces the number of template instantiations and so reduces
memory usage.

Make std::function tolerate semantically non-CopyConstructible objects
...
To satisfy the CopyConstructible requirement a callable object stored in
a std::function must behave the same when copied from a const or
non-const source. If copying a non-const object doesn't produce an
equivalent copy then the behaviour is undefined. But we can make our
std::function more tolerant of such objects by ensuring we always copy
from a const lvalue.
Additionally use an if constexpr statement in the _M_get_pointer
function to avoid unnecessary instantiations in the discarded branch.

PR libstdc++/78420 Make std::less etc. yield total order for pointers
...
In order for std::less<T*> etc. to meet the total order requirements of
[comparisons] p2 we need to cast unrelated pointers to uintptr_t before
comparing them. Those casts aren't allowed in constant expressions, so
only cast when __builtin_constant_p says the result of the comparison is
not a compile-time constant (because the arguments are not constants, or
the result of the comparison is unspecified). When the result is
constant just compare the pointers directly without casting.
This ensures that the function can be called in constant expressions
with suitable arguments, but still yields a total order even for
otherwise unspecified pointer comparisons.
For std::less<void> etc. add new overloads for pointers, which use
std::less<common_type_t<T*,U*>> directly. Also change the generic
overloads to detect when the comparison would call a built-in relational
operator with pointer operands, and dispatch that case to the
corresponding specialization for void pointers.
