Complete the checks for distinguishable specifics procedure in a generic
by considering any passed-object dummy arguments.
C1514 rule 3 is implemented and the checks for the other rules are
extended to consider the PASS attribute, including the concept of the
"effective" position of an argument in an argument list, computed by
ignoring passed-object arguments.
Add `pass` to `characteristics::DummyArgument` to mark each
passed-object dummy argument.
Change symbols to store the index of the passed-object dummy argument
rather than its symbol.
Check that specifics of a type-bound generic are distinguishable only
after all of the procedure bindings have been processed. They don't have
to be before the generic.

In `OrderParameterNames` and `OrderParameterDeclarations` it was
always true that `this == &type.get<DerivedTypeDetails>()` which
meant that `this` was redundant.
So convert them to non-member functions in `tools.h` that get the
details from the symbol passed in. This makes life simpler for the
callers.

Move these functions from scope.cc, symbol.cc, type.cc into tools.cc:
Scope::FindOrInstantiateDerivedType
Scope::InstantiateDerivedType
Scope::InstantiateIntrinsicType
Symbol::Instantiate
DerivedTypeSpec::ProcessParameterExpressions
DerivedTypeSpec::Instantiate
This eliminates some dependencies in these files on SemanticsContext,
FoldingContext, etc.
It also allows three of the functions to be private to tools.cc
because they are only called from the others.

- Changed the name a a function to FindOrDeclareEnclosingEntity
- Changed that function to return a reference rather than a pointer
- Polished the setting of the IMPLICIT flag on a declared entity in a
locality-spec
- Changed a test to remove an unreported error

Prior to this change, the compiler issued an error message when a name in a
SHARED locality-spec had not been declared explicitly in an enclosing scope.
Presumably, this was done to enforce constraint C1124. This constraint states
that "A variable-name in a locality-spec shall be the name of a variable in the
innermost executable construct or scoping unit that includes the DO CONCURRENT
statement". For LOCAL and LOCAL_INIT locality-spec's, we were automatically
creating a local variable in the situation where one had not been explicitly
declared rather than issuing an error message.
The only compiler I could find that implements the SHARED locality-spec was the
PGI compiler, which automatically creates a variable and does not emit an error
message. Also, @vdonaldson said that he had consulted with a member of the
Fortran standards committee who said that the correct thing was to create a
variable if necessary.
This change has the compiler creating a variable in the enclosing scope of a DO
CONCURRENT statement if necessary. I also changed a test to adapt to the new
behavior. I also consolidated the semantic checking for the constraints
associated with all of the locality-spec's.

Straightforward implementation but not including:
* list-item on aligned clause
* nesting check with the ordered construct (parse tree changes needed!)
* list-item attributes check on aligned clause
