281d41cc10 [flang] Use value semantic for SourceName 
Change all SourceName* to std::optional<SourceName> because
SourceName is small enough (16 bytes) to be passed and stored
by value which avoid having to worry about life-time, storage and
value constance issues that comes with pointers.

d151b5e88b [flang] Fix bug writing character array constructor to .mod file 
Character literals in an array constructor were always written
with no kind prefix, so if kind was not 1 they were incorrect.
`c4a` in `modfile28.f90` was an example of this.

Change it to always include the kind as is done with non-array
character literals.

331c04cce6 [flang] Change ArraySpec from a type alias to a class 
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.

ba7ed2722a [flang] Fix extended derived type kind compatibility check 
`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.

97e60b7354 [flang] Procedure distinguishability rules for operators 
Generic operators and assignment have different rules than generic
names for their procedures being distinguishable.

Implement those rules in `DistinguishableOpOrAssign`. The rules are
considerably simpler: they must have the name number of dummy arguments
and at least one pair in the same position must be distinguishable.

Fixes issue flang-compiler/f18#563.

714d3be8bf [flang] Use passed-object dummy in distinguishability checks 
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.
