feat(parser): Treat contractions as a word

This should be safe.  Rarely is `'` used as syntax in a language that
separates literals.

- `'` is used within hex literals in C++ but we want to treat them as
  one word
- `'` is used for lifetimes in Rust but there are other symbols on the
  left side.
