91cfacc4b5 libstdc++: Disable std::array assertions for C++11 constexpr 
The recent changes to add assertions to std::array broke the functions
that need to be constexpr in C++11, because of the restrictive rules for
constexpr functions in C++11.

This simply disables the assertions for C++11 mode, so the functions can
be constexpr again.

libstdc++-v3/ChangeLog:

	* include/std/array (array::operator[](size_t) const, array::front() const)
	(array::back() const) [__cplusplus == 201103]: Disable
	assertions.
	* testsuite/23_containers/array/element_access/constexpr_element_access.cc:
	Check for correct values.
	* testsuite/23_containers/array/tuple_interface/get_neg.cc:
	Adjust dg-error line numbers.
	* testsuite/23_containers/array/debug/constexpr_c++11.cc: New test.

2f983fa690 libstdc++: Fix three-way comparison for std::array [PR 96851] 
The spaceship operator for std::array uses memcmp when the
__is_byte<value_type> trait is true, but memcmp isn't usable in
constexpr contexts. Also, memcmp should only be used for unsigned byte
types, because it gives the wrong answer for signed chars with negative
values.

We can simply check std::is_constant_evaluated() so that we don't use
memcmp during constant evaluation.

To fix the problem of using memcmp for inappropriate types, this patch
adds new __is_memcmp_ordered and __is_memcmp_ordered_with traits. These
say whether using memcmp will give the right answer for ordering
operations such as lexicographical_compare and three-way comparisons.
The new traits can be used in several places, and can also be used to
implement my suggestion in PR 93059 comment 37 to use memcmp for
unsigned integers larger than one byte on big endian targets.

libstdc++-v3/ChangeLog:

	PR libstdc++/96851
	* include/bits/cpp_type_traits.h (__is_memcmp_ordered):
	New trait that says if memcmp can be used for ordering.
	(__is_memcmp_ordered_with): Likewise, for two types.
	* include/bits/deque.tcc (__lex_cmp_dit): Use new traits
	instead of __is_byte and __numeric_traits.
	(__lexicographical_compare_aux1): Likewise.

	Likewise.
	* include/bits/stl_algobase.h (__lexicographical_compare_aux1)
	(__is_byte_iter): Likewise.
	* include/std/array (operator<=>): Likewise. Only use memcmp
	when std::is_constant_evaluated() is false.
	* testsuite/23_containers/array/comparison_operators/96851.cc:
	New test.
	* testsuite/23_containers/array/tuple_interface/get_neg.cc:
	Adjust dg-error line numbers.

3a4cc6281b libstdc++: Implement spaceship for std::array (P1614R2) 
As done for std::pair, this defines operator<=> as a non-member function
template and does not alter operator==, as expected to be proposed as
the resolution to an unpublished LWG issue.

Instead of calling std::lexicographical_compare_three_way the <=>
overload is implemented by hand to take advantage of the fact the
element types and array sizes are known to be the same.

	* include/bits/cpp_type_traits.h (__is_byte<char8_t>): Add
	specialization.
	* include/std/array (operator<=>): Likewise.
	* testsuite/23_containers/array/comparison_operators/constexpr.cc:
