When a macro generates part of the derive input, the call-site hygiene
may be different than the hygiene of a field. Therefore, we need to
be sure to use the same hygiene information for any identifiers we
generate, instead of relying on the hygiene from a particular span
via `quote_spanned!`
Apparently this is fine in 1.39 and up, but older compilers warn.
