  Log Message:
  -----------
  [libc++] Don't assume that string_view::const_iterator is a raw pointer

Our implementation of std::format assumed that string_view's iterators
were raw pointers in various places. If we want to introduce a checked
iterator in debug mode, that won't be true anymore. This patch removes
that assumption.
