Lex: Fix an invalid access into a SmallString
We would crash because we used operator[] to access past the end of a
SmallString. This occured because our token had length zero.
Instead, form the pointer using .data() and arithmetic. This is safe
because this forms a one-past-the-end pointer and it is only used to
compare with another one-past-the-end pointer.
This fixes PR21379.
