runtime: when panicking, skip ahead to previous panic
While looking up the stack for a defer to run, if we come across
a panic frame we can skip ahead (up) to where the previous panic
was looking for a defer to run.
Switch from keeping LR (the caller's pc) to PC (the frame's PC).
Seems easier to reason about.
Fixes #77062
