Added handling for noreturn std functions.
The C11 standard declares exit,abort,_Exit,quick_exit and
thrd_exit as _Noreturn however this is not included in older C
libs and leads to false negatives in reporting _Noreturn and
return type warnings. This can be avoided by enhancing the
noreturn check of the Cflow analysis to also test if one of the
above functions is called.
