There were many places in tests and predefined modules that had
incorrect code that we weren't detecting until now.
Most of the problems were deferred-shape arrays that should have
been implied-shape. For example:
`real, parameter :: a(:) = [1.0, 2.0]`
should have `(*)` rather than `(:)`.
There were also a few places with deferred-shape arrays that were
not allocatable/pointer or explicit-shape ones that were.

There are many constraints on what kind of array-specs can appear
in what contexts. Add `CheckArraySpec()` to perform most of them.
When the check fails, don't set the shape of the symbol being
declared and instead set the Error flag so we can avoid cascading
errors.
Fixesflang-compiler/f18#609.

This allows it to have member functions `Rank()`, `IsExplicitShape()`,
`IsAssumedShape()`, etc. Make use of those new functions and remove
`isExplicit()` and `isDeferred()` from `ShapeSpec` as they are no
longer needed.

An array-spec like `(:,:)` (with one or more colons) is either a
deferred-shape-spec-list or an assumed-shape-spec-list and they
can only be distinguished by context that the parser doesn't have.
We were parsing these as assumed-shape-spec-list but they are easier
to deal with if we parse them as deferred-shape-spec-list because
anything that is the latter is also one of the former.

- make `TypaParamAttr` a `ParamValue` argument. Modify
`GetParamValue` to also take this as an argument.
- remove `GetLenParamValue` that is now useless and
modify constructor/`GetParamValue` calls
- get it the `TypeParamAttr` right from the begining
when visiting `parser::DerivedTypeSpec` in resolve-names.cc.
It was set to `Kind` by default and it was hard to ensure the
attribute would not be checked until set properly.

While testing fix for issue 581 it appeared that 'ParamValue`
implicit len parameters had incorrect attribute kind.
This commit:
+ Set correct attribute when creating `ParamValue` for implicit
type parameter.
+ Also set the correct attribute foe charachter lenght `ParamValue`
though it is currently not used anywhere.
+ Change some std::int64_t to common::ConstantSubscript on the way.

`HaveCompatibleKindParameters` was not considering the kind
parameters of the parent types leading to false answers.
This change fixes this by directly looking into the map of `ParamValue`
of the `DeclTypeSpec` instead of going through the symbols of the derived
type scope. This map contains all the parent and implicit type parameters.

* [OpenMP] parse tree changes for standalone directives
1. Put all standalone directives except FLUSH, CANCEL, and CANCELLATION POINT
into one `OpenMPSimpleStandaloneConstruct` (for no-clause directive,
validity checks will be deferred to Semantics). A top-level class will
include all the standalone directive nodes. This simplies the logic a lot.
2. All the standalone directives now have their own source provenance for
directive name itself.
3. Change check-omp-structure.* to avoid assertions
4. Add basic tests for standalone directives, more will be added during
the clause validity checks in Semantics
* Resolve !$OMP ORDERED ambiguity by attempting block construct first - Peter

- dosemantics05.f90: Added tests for ASSOCIATE, BLOCK and SELECT TYPE statements and changed the error messages.
- check-do.cc: Changed things so that FindScope() is only called once when DoConcurrentVariableEnforce is instantiated. I changed the error message. I changed the type and name of CS to be an std::set and be called SymbolContainer.
- resolve-names.cc: I changed the Pre() function for parser::Statement to add the source range of a statement to both the current scope and all of its parents. This fixed a problem with finding the current scope based on the source position.

The constraint states that "If the locality-spec DEFAULT ( NONE ) appears in a DO CONCURRENT statement; a variable that is a local or construct entity of a scope containing the DO CONCURRENT construct; and that appears in the block of the construct; shall have its locality explicitly specified by that statement."
Here's a summary of the changes:
- In check-do.cc: Implemented the function
CheckDefaultNoneImpliesExplicitLocality() to do the checking. This involved
adding the class DoConcurrentVariableEnforce to walk the DO loop's block
looking for variable names. I also cleaned up the code a little in
CheckDoExpression() and EnforceConcurrentLoopControl().
- Added the test dosemantics05.f90

1. Changes are to save provenance for directive names
2. check-omp-structure.* is updated to avoid assertion errors
3. Tests added now are only for the basic usages for the declarative directives,
more complete examples will be added once we start implementing the semantics

* [OpenMP] Add Sections and Single Construct check
Parse tree for OmpEndSingle needs to be modified to save the provenance
of END SINGLE directive and check its own clauses
* Update on reviews
1. PushContext is created to push new context with source provenance
2. Tweak the logic for SECTION nesting, treak Orphaned or wrong nesting
as the same error type
3. Make sure the check for NOWAIT clause only applies to the ones that
are not handled by parser.
Note that the case for DO or DO_SIMD will take effect after the
loop association work (parse tree change) is done. But I still list
them there for completeness.
4. Happen to find that NOWAIT is not accepted by PARALLEL SECTIONS,
fixed it in the parser.

When we use-associate a generic interface name and then add more
procedures to the generic, we create a new symbol for the merged
generic. That symbol has to include a pointer to the derived type
or procedure with the same name, just as the original generic did.
To achieve that, change `AddSpecificProcsFrom` to also copy those
fields from the original symbol and change its name to `CopyFrom`
to reflect its new purpose. Also, change it to take `GenericDetails`
instead of `Symbol` as its argument so we can't call it on the wrong
kind of symbol.

When a generic interface had no specific procedures, we were writing
it the `.mod` file as `generic::g=>`, which is not valid Fortran.
Change to writing generics as interface blocks rather than generic
statements so that this case is handled. Include an access stmt if it
was declared private.
Also fix a bug in `test_errors.sh` where the expected/actual error
messages weren't sorted by line number correctly.
