PptTopLevel.normalize_type derives the type from the name when the declaration gives no type, or gives the type exit or point, so the is_enter, is_exit, is_combined_exit, is_subexit, is_object, and is_class predicates no longer need name-based fallbacks. A numbered exit declared with type exit is a subexit. * Daikon.create_combined_exits does not replace a declared combined exit. * AnnotateNullable handles an .inv file that lacks a combined exit. * PptConditional takes its parent's type. Split from codespecs#858.

- Around line 460-479: Update normalize_type to classify every name recognized
by PptName.isExitPoint() as an exit, returning EXIT for combined exit points and
SUBEXIT for other exit points; preserve the existing explicit-type handling and
remaining name classifications.

* A missing ppt-type is derived from the name; an explicit "point" is kept. * A ppt declared exit or subexit is a combined or numbered exit according to its name; any other declared type must conform to the name, or reading the declaration fails with an error. * Remove backward-compatibility code for older .inv files. * Daikon.create_combined_exits again replaces a declared combined exit. * Remove PptName.isExitWithLineNumber; use isNumberedExitPoint.

PptTopLevel.normalize_type, from codespecs#876, checks a declared type against the program point's name, so FileIO.parse_ppt_type no longer does. The type-based is_dataflow_leaf replaces share-hierarchy's name-based one.

This is one of three PRs split from #858. It is independent of #875; #877 depends on both. It makes the program point type predicates (
is_enter,is_exit,is_combined_exit,is_subexit,is_object,is_class) consistent. It replaces #871.Previously, each predicate used the declared program point type when there was one, and otherwise the name. Declared types are not always consistent with the name: some front ends declare a numbered exit such as
foo:::EXIT22withppt-type exit, which made it a combined exit. NowPptTopLevel.normalize_typedetermines each program point's type, and the predicates use only the type:exitorsubexitis a combined exit (foo:::EXIT) or a numbered exit (foo:::EXIT<id>), according to its name.pointkeeps that type, whatever its name.enter,object, orclasskeeps that type, but its name must conform to the type, as the developer manual requires. Otherwise, reading the declaration fails with an error.To distinguish a missing
ppt-typerecord fromppt-type point,FileIOno longer defaults the type topoint. APptConditionaltakes its parent's type.In the
KnownValues,KnownValuesNewDecls, andNonZeroLargeRangetests, the numbered exits are declared withppt-type exit. They are now subexits, so Daikon creates their combined exit, and the goal files report invariants at:::EXITrather than:::EXIT1.
