[flang] Changes to improve messages for DO semantics

I changed two things in the messages produced for DO semantic checks --
 - I changed the source location to be specific to where conflicting names are
 declared.
 - I added the conflicting names to the message.

[flang] Fix CHECK failure on undeclared type parameter

In the example below, the compiler gets an internal error when
processing the derived-type-spec for the declaration of `x`.
When the search for type parameter `k` fails it means an error
has already occurred and we should skip that parameter.

```
type :: t(k)
end type
type(t):: x
end
```

[flang] These changes are in response to comments on my pull request for C1123.

Here's a summary of the changes:
 - I renamed a function to ResolveControlExpressions for clarity.
 - I changed the interface to the function to ResolveIndexName for clarity.
 - I simplified the code for walking the "step" and scalar mask expressions in
   a DO CONCURRENT control statements to not check for the presence of optional
   expressions.
 - I added "const" to the declaration of a local variable.
 - I removed some spurious comments from the test dosemantics04.f90.
 - I added two new tests to dosemantics04.f90 to verify cases that were not
   covered in my original test implementation.

[flang] I fixed a problem in C1123.  This constraint requires that expressions in a DO
CONCURRENT header not reference names declared in the same header.  To
implement this, I changed the "Pre" function for ConcurrentHeader to walk the
subtree in an order that caused the variables associated with the declared
names to be created before any of the expressions were walked.

I added the test dosemantics04.f90 to test this.

[flang] Handle nested interface blocks

Interface blocks can be nested if one of the interface bodies
declares a subprogram with a dummy procedure that is specified
by an interface block. See the addition to `modfile07.f90` for
and example.

This didn't work because there was only one copy of each of
`inInterfaceBlock_`, `isAbstract_`, and `genericSymbol_`.
We need these for each active interface block, so replace these
with a stack. A new entry is pushed on the stack when we enter
an `InterfaceStmt` or `GenericStmt` and popped when we leave.

Also in the same example, when declaring the dummy procedure, the
dummy argument is initially an `EntityDetails` but it is replaced
by a `SubprogramDetails` when it is specified by the interface.

A substring of an array element is legal as an equivalence object,
e.g. `a(2,3)[4:5]`. Extend `EquivalenceObject` to include the start
of the substring, if any. Split `CheckBound` into `CheckArrayBound`
and `CheckSubstringBound`.

When evaluating bounds in `AddToSet` we can assert they are constant
because all of the error cases should have been detected already.

[flang] Resolve and check names in equivalence sets

Collect sets of `parser::EquivalenceObject` to process at the end of
the specification part. This is so that names mentioned in the
EQUIVALENCE statement don't trigger implicit declarations.

The `EquivalenceSets` class performs most of the numerous checks
on objects that can be in equivalence sets at all and objects that
can be in them together. It also merges sets when the same object
appears in more than one.

Once equivalence sets are checked they are added to the `Scope`.
Further checks will be necessary after the size and alignment of
variables are computed.

Add `FindUltimateComponent` to simplify checks on ultimate components
of derived types. Use it to implement `HasCoarrayUltimateComponent`
and checks on equivalence objects.

Make `ExpressionAnalyzer::Analyze(Designator)` public so that
`parser::EquivalenceObject` can be analyzed.

Add `GetDefaultKind`, `doublePrecisionKind`, and `quadPrecisionKind`
to `SemanticsContext` so that `defaultKinds_` does not need to be
accessed directly.

[flang] These are additional changes for issue 458, to perform semantic checks on DO
variable and initial, final, and step expressions.

Here's a summary of the changes since my original pull request:

 - I've taken into account the possibility that the DO variable is declared in
   a MODULE.  This required a call to GetUltimate() on the Symbol for the DO
   variable.
 - The previous change exposed problems in the semantic checking for NULLIFY
   and DEALLOCATE statements, so I've included fixes and tests for those.  I
   also added a test for the ALLOCATE statement, even though it was already
   handling this case.
 - I now handle the case where a procedure name is erroneously used as a DO variable.
 - I now handle the case where a pointer to a procedure is erroneously used as
   a DO variable.
 - I now check that the DO expressions are not null.
 - I added tests for all cases listed above.

[flang] These changes are for issue 458, to perform semantic checks on DO variable
and initial, final, and step expressions.  As a new extension, we want to allow
REAL and DOUBLE PRECISION values for them by default.

Here's a summary of the changes:
 - There already existed infrastructure for semantic checking of DO loops that
   was partially specific to DO CONCURRENT loops.  Because I re-used some of
   this infrastructure, I renamed some files and classes from "concurrent" to
   "stmt".
 - I added some functions to distinguish among the different kinds of DO
   statements.
 - I added the functions to check-do-stmt.cc to produce the necessary warnins
   and errors.  Note that there are no tests for the warnings since the
   necessary testing infrastructure does not yet exist.
 - I changed test-errors.sh so that additional compilation options can be
   specified in the test source.
 - I added two new tests to test for the various kinds of values that can be
   used for the DO variables and control expressions.  The two tests are
   identical except for the use of different compilation options.
   dosemantics03.f90 specifies the options "-Mstandard -Werror" to produce
   error messages for the use of REAL and DOUBLE PRECISION DO variables and
   controls.  dosemantics04.f90 uses the default options and only produces
   error messages for contructs that are erroneous by default.

[flang] Fix issue flang-compiler/f18#486

In a function without a function result specified, the name in the
`FunctionStmt` was resolved to the function result symbol rather than
the function symbol itself. That is inconsistent with subroutines and
other functions.

The fix is to explicitly set the function name symbol after the result
has been resolved.
