parser+lexer: Add proper counting of line numbers
...
Since the compiler is two-pass, having the incrementation performed in
the lexer would result in extraneous incrementations during the
preprocessing phase. We want line numbers for diagnostics during the
parsing phase and therefore a fix would be to have the parser filter
newlines out itself.
