Also refactor the diagnostics so that we print out the kind of stack memory returned.

by inspecting the Store bindings instead of iterating over all the global variables
in a translation unit.  By looking at the store directly, we avoid cases where we cannot
directly load from the global variable, such as an array (which can result in an assertion failure)
and it also catches cases where we store stack addresses to non-scalar globals.
Also, but not iterating over all the globals in the translation unit, we maintain cache
locality, and the complexity of the checker becomes restricted to the complexity of the
analyzed function, and doesn't scale with the size of the translation unit.

This fixes PR 7383.

improves generality. Thanks Ted.

the function call is left where the local variable is declared.
