In plist output mode with alternate path diagnostics, when entering a function,
we draw an arrow from the caller to the beginning of the callee's declaration.
Upon exiting, however, we draw the arrow from the last statement in the
callee function. The former makes little sense when the declaration is
not a definition, i.e. has no body, which may happen in case the body
is coming from a body farm, eg. Objective-C autosynthesized property accessor.

Nullable-to-nonnull checks used to crash when the custom bug visitor was trying
to add its notes to autosynthesized accessors of Objective-C properties.
Now we avoid this, mostly automatically outside of checker control, by
moving the diagnostic to the parent stack frame where the accessor has been
called.
