[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.

[flang] Changes to add an executable construct stack
I added a stack of ExecutableConstruct's to SemanticsContext along with
functions to push and pop constructs.  I added code to the SemanticsVisitor
to use these new functions.  I also added functions Pre and Post functions
for UnlabeledStatement's so that we could isolate the source positions for
statements embedded in "if" statements to improve error messages.

I also added code to check-do.[h,cc] to use this new infrastructure to check
for CYCLE and EXIT statements that are not contained within DO constructs
along with a test.

Name resolution for Cray pointers

[flang] Name resolution for Cray pointers

Resolve the pointer and pointee names in a `BasedPointerStmt` and
enforce some of the constraints on them. There are still some
constraints to be implemented, mainly about what kind of attributes
the pointers and pointees can have.

The rules for these are a little vague. I mostly followed
- Cray Fortran Reference Manual section 9.3.2
- https://gcc.gnu.org/onlinedocs/gfortran/Cray-pointers.html
- VSI Fortran for OpenVMS Language Reference Manual section B.11

Note that the first two use the term "Cray pointer" but the last does
not. That is confusing because you have to know from context whether
it is referring to Cray pointers or Fortran pointers, so I used
"Cray pointer" and "Cray pointee" in error messages to refer to the
two names in the pointer statement.

Fix declaration of module procedure subprograms

[flang] Fix declaration of module procedure subprograms

Names of subprograms declared with MODULE PROCEDURE in a submodule
were not found correctly. The fix is to separate the handling of
these from other subprograms. The subprogram being defined must have
been declared in the same module or an ancestor module/submodule.
