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.
