Function rustc_typeck::check::upvar::restrict_precision_for_unsafe

fn restrict_precision_for_unsafe<'tcx>(place: Place<'tcx>) -> Place<'tcx>

• No projections are applied to raw pointers, since these require unsafe blocks. We capture them completely.
• No projections are applied on top of Union ADTs, since these require unsafe blocks.
