* Overall syntax highlighting improvements for C++ Most of these changes are based on the information on cppreference.com; specifically from here: https://en.cppreference.com/w/cpp/keyword - made `identifier` actually match any identifier - add ~ as an operator - add `static_assert` as a keyword (statement) - add keywords that are interchangeable with operators as operators - add keywords `sizeof`, `alignof` and `typeid` as operators - add the quasi-keywords `asm`, `fortran` and `final`, `override` - add the keyword `nullptr` - add `_Pragma` as a preprocessor keyword - add C++20 (concepts and modules) -related keywords - add casting keywords - add the keyword (specifier) `noexcept` - remove `nothrow` (because it's not any more special than `vector` is) - add `wchar_t` and `charXX_t` types - add cv type keywords as `type.keyword`s - move some fitting keywords into `type.keywords` (mostly because they appear in/near type signatures etc.) I didn't include coroutine-related language features, primarily because there is no good source of information about them other than the ISO C++ standard. * Further changes to C++ syntax highlighting - reverted the changes to the `identifier` regex, since most colorschemes color it the same as `type`s and/or `statement`s - fix the 2nd `type` regex (the word boundaries were in only two pipe-options) - move `nullptr` back into `constant.bool`, since it looks better in-editor this way (imo) - add `?` as an operator - add regexes that match all the correct number literals, and nothing else (see https://en.cppreference.com/w/cpp/language/floating_literal) (that is, if I haven't made a mistake)
