This patch is to show the framework to do OpenMP structure related check and you may find missing/incomplete implementation, which will be added in the future.
1. Each encountering construct has its own context and the context info will be filled while walking the directive/clause nodes. In the `Leave`, the current OpenMP context will be popped out.
2. When entering the construct, necessary nesting check will be performed. Use std::vector to implement the context stack because certain nesting restrictions may need to trace back more than one level.
3. PARALLEL construct is used as an example for clause validity check.
4. `EnumSet` is used to represent the directive/clause sets and to show the error msg. All the error msgs are quoted from the specification.
5. Necessary `CharBlock` is added for error msgs.

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.

Use better names for template parameters of `LoopBounds`, and also
for the constructor arguments.
Use two overloadings of `loopBounds()` instead of `std::is_same_v<>`.

It is a common extension to allow DO loops with REAL variable and
bounds. The parse tree currently parses those with the variable
as `scalar-int-variable-name` and the bounds as `scalar-int-expr`.
That causes the INTEGER constraint to be enforced automatically.
Change the grammar and parse tree to treat them as `scalar-variable-name`
and `scalar-expr`. This allows the name and expression to be REAL,
but we will have to verify that they aren't any other type (in a future
change).
To accomplish this, add a template parameter to `LoopBounds` for the type
of the variable name (always `Scalar<Name>` or `Scalar<Integer<Name>>`).
We sometimes need names for the instantiations of `LoopBounds` so add
type aliases like `LoopControl::Bounds` for each one.
