David Majnemer d3c3e78ac1 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.
