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.

The create_dir helper was calling the throwing form of
filesystem::is_directory instead of passing the error_code argument.
Since std::filesystem::create_directory(const path&, error_code&) is
noexcept, it would call std::terminate if an error occurred in
is_directory.
Passing the error_code also takes care of clearing it in the case where
is_directory returns true.

ENDBR32 and RDSSPD are multi-byte NOPs on x86-64 processors and
newer x86 processors, starting Pentium Pro. They are UD on older
32-bit processors. Detect this at configure time and adjust the
