Function is_sliceindex_get_unchecked 

pub fn is_sliceindex_get_unchecked(callee: Option<DefId>) -> bool

Whether callee is SliceIndex::get_unchecked/get_unchecked_mut (the trait method, whose receiver is the index and whose first argument is the slice pointer). Distinct from is_slice_get_unchecked (the slice-side methods whose receiver is the slice): the result aliases argument 1, not argument 0.
