The parser cursor should skip line terminators by default

[Razican]

Line terminators are almost always just a simple white space. The lexer needs to take them into account to allow automatic semicolon insertion and allow checking for places where line terminators are not allowed.

So, in this scenario, I would propose for the parser cursor to automatically skip line terminators when calling next(), peek() or expect(). We already have a expect_semicolon() function that will take into account line terminators. We would also need a peek_semicolon() that would check if a semicolon could be inserted (or is present), to check for things such as continue; or continue expr;.

Finally, we would need another expect_no_lineterminator() function, that would make sure that there is no line terminator at the given position. I think this would make it easier to implement the spec, or at least our parsing code would be closer to what we see in the spec.

This would also allow removing the skip() function, the {peek/next}_skip_lineterminator() functions, and review the next_if() functions, since there seems to be a lot of duplicated functionality here.

Don't we skip line terminators in #304 by default?

Yes! This is solved :)
