Add noreturn attribute to crash()

Since crash() stops the program, adding the `noreturn` attribute allows the compiler to optimize in certain cases. CLion and ReSharper also use this in its static analysis engine to warn about unreachable code. Additionally, since `assert()` uses `crash()` if the checked pointer is null, this lets the analysis engine correctly discern that the pointer will in fact not be null and stop erroneous null pointer warnings.
