Log:
PR libstdc++/79980 fix BOM detection, maxcode checks, UCS2 handling
PR libstdc++/79980
* include/bits/locale_conv.h (__do_str_codecvt): Set __count on
error path.
* src/c++11/codecvt.cc (operator&=, operator|=, operator~): Overloads
for manipulating codecvt_mode values.
(read_utf16_bom): Compare input to BOM constants instead of integral
constants that depend on endianness. Take mode parameter by
reference and adjust it, to distinguish between no BOM present and
UTF-16BE BOM present.
(ucs4_in, ucs2_span, ucs4_span): Adjust calls to read_utf16_bom.
(surrogates): New enumeration type.
(utf16_in, utf16_out): Add surrogates parameter to choose between
UTF-16 and UCS2 behaviour.
(utf16_span, ucs2_span): Use std::min not std::max.
(ucs2_out): Use std::min not std::max. Disallow surrogate pairs.
(ucs2_in): Likewise. Adjust calls to read_utf16_bom.
* testsuite/22_locale/codecvt/codecvt_utf16/79980.cc: New test.
* testsuite/22_locale/codecvt/codecvt_utf8/79980.cc: New test.
