    A libcxx/test/libcxx/strings/string.view/assert.ctor.length.pass.cpp

  Log Message:
  -----------
  [libc++] Assert that lengths fit in difference_type

This can help flag accidentally passing in negative values into the  `string_view` constructor. This aligns with a similar check in `absl::string_view`.
