When we pass function arguments on the stack, untagged parameters
"come first", i.e. are put to lower addresses / can be popped off
first. So when a function instructs the stack walker to visit its
parameters (belonging to its caller's frame), it must skip past
any untagged parameters at the top of the caller's frame.
