libcpp: Add -Winvalid-utf8 warning [PR106655]
The following patch introduces a new warning - -Winvalid-utf8 similarly
to what clang now has - to diagnose invalid UTF-8 byte sequences in
comments, but not just in those, but also in string/character literals
and outside of them.
The warning is on by default when explicit -finput-charset=UTF-8 is
used and C++23 compilation is requested and if -{,W}pedantic or
-pedantic-errors it is actually a pedwarn.
The reason it is on by default only for -finput-charset=UTF-8 is
that the sources often are UTF-8, but sometimes could be some ASCII
compatible single byte encoding where non-ASCII characters only
appear in comments. So having the warning off by default
is IMO desirable. The C++23 pedantic mode for when the source code
is UTF-8 is -std=c++23 -pedantic-errors -finput-charset=UTF-8.

and cpp_input_charset_explicit.
* charset.cc (_cpp_valid_utf8): Adjust function comment.
* lex.cc (UCS_LIMIT): Define.
(utf8_continuation): New const variable.
(utf8_signifier): Move earlier in the file.
(_cpp_warn_invalid_utf8, _cpp_handle_multibyte_utf8): New functions.

* c-opts.cc (c_common_handle_option) <case OPT_finput_charset_>:
Set cpp_opts->cpp_input_charset_explicit.
(c_common_post_options): If -finput-charset=UTF-8 is explicit
in C++23, enable -Winvalid-utf8 by default and if -pedantic
or -pedantic-errors, make it a pedwarn.
