Add new helper traits for signed/unsigned integer types
Reuse the __is_one_of alias in additional places, and define traits to check for signed/unsigned integer types so we don't have to duplicate those checks elsewhere. The additional overloads for std::byte in <bit> were reviewed by LEWG and considered undesirable, so this patch removes them. * include/bits/fs_path.h (path::__is_encoded_char): Use __is_one_of. * include/std/bit (_If_is_unsigned_integer_type): Remove. (_If_is_unsigned_integer): Use __is_unsigned_integer. (rotl(byte, unsigned), rotr(byte, unsigned), countl_zero(byte)) (countl_one(byte), countr_zero(byte), countr_one(byte)) (popcount(byte), ispow2(byte), ceil2(byte), floor2(byte)) (log2p1(byte)): Remove. * include/std/charconv (__detail::__is_one_of): Move to <type_traits>. (__detail::__is_int_to_chars_type): Remove. (__detail::__integer_to_chars_result_type): Use __is_signed_integer and __is_unsigned_integer. * include/std/type_traits (__is_one_of): Move here from <charconv>. (__is_signed_integer, __is_unsigned_integer): New helpers. * testsuite/26_numerics/bit/bit.pow.two/ceil2.cc: Remove test for std::byte overload. * testsuite/26_numerics/bit/bit.pow.two/floor2.cc: Likewise. * testsuite/26_numerics/bit/bit.pow.two/ispow2.cc: Likewise. * testsuite/26_numerics/bit/bit.pow.two/log2p1.cc: Likewise. * testsuite/26_numerics/bit/bitops.count/countl_one.cc: Likewise. * testsuite/26_numerics/bit/bitops.count/countl_zero.cc: Likewise. * testsuite/26_numerics/bit/bitops.count/countr_one.cc: Likewise. * testsuite/26_numerics/bit/bitops.count/countr_zero.cc: Likewise. * testsuite/26_numerics/bit/bitops.count/popcount.cc: Likewise. * testsuite/26_numerics/bit/bitops.rot/rotl.cc: Likewise. * testsuite/26_numerics/bit/bitops.rot/rotr.cc: Likewise.
