bug

__has_include with angle-bracketed argument breaks preprocessing

Preprocessing (in C++17 mode) of code like this: ```cpp #if __has_include() #endif ``` results in an error: ``` /tmp/fail.cpp:1: syntax error: failed to evaluate #if condition ``` This happens regardless...

skip all code inside #if 0

Code inside `#if 0` should be skipped: ``` #if 0 ' #endif ``` simplecpp output: `1.c:2: syntax error: No pair for character ('). Can't process file. File is either invalid...

run tests with `std::istringstream`,`std::ifstream`, buffer and file input

added `TokenList::Stream` class to wrap `std::istream` usage and implemented alternative C I/O version

Reading the file via `std::istream` includes a considerable overhead caused by `std::istream::sentry` and others. Using C I/O instead reduces the "total Ir" usage by about 10%. Testing with `-q -Ilib/...

firewave

added clang-tidy CI job and fixed warnings / added CMake option "DISABLE_CPP03_SYNTAX_CHECK" / CMake cleanups

The only interesting suppress warning is currently `clang-analyzer-core.NullDereference` since it depends on very complex value flow, might be a false positive and I didn't have the time to review it.
