[flang] Responses to review comments and team meeting

The most significant change is that I replaced the stack of
ExecutableConstruct's with a stack composed of ConstructNode's, each of which
is a variant of the constructs that made up the type ExecutableConstruct.  This
change allows the nodes of the stack to be extended to include the types needed
for OMP semantic checking.

I also extended the existing test to include some correct DO loops with CYCLE
and EXIT statements to test the code more completely.
