Motivation:
- simplify implementation of lazy type checking
- fix correctness issues of lazy type checking (#785)
Changes:
- implement listing/mapping type cast via amendment (`parent`) instead of delegation (`delegate`)
- handle type checking of *computed* elements/entries in the same way as type checking of computed properties
- ElementOrEntryNode is the equivalent of TypeCheckedPropertyNode
- remove fields VmListingOrMapping.delegate/typeNodeFrame/cachedMembers/checkedMembers
- fix #785 by executing all type casts between a member's owner and receiver
- fix #823 by storing owner and receiver directly
instead of storing the mutable frame containing them (typeNodeFrame)
- remove overrides of VmObject methods that are no longer required
- good for Truffle partial evaluation and JVM inlining
- revert a85a173faa except for added tests
- move `VmUtils.setOwner` and `VmUtils.setReceiver` and make them private
- these methods aren't generally safe to use
Result:
- simpler code with greater optimization potential
- VmListingOrMapping can now have both a type node and new members
- fewer changes to surrounding code
- smaller memory footprint
- better performance in some cases
- fixes https://github.com/apple/pkl/issues/785
- fixes https://github.com/apple/pkl/issues/823
Potential future optimizations:
- avoid lazy type checking overhead for untyped listings/mappings
- improve efficiency of forcing a typed listing/mapping
- currently, lazy type checking will traverse the parent chain once per member,
reducing the performance benefit of shallow-forcing
a listing/mapping over evaluating each member individually
- avoid creating an intermediate untyped listing/mapping in the following cases:
- `new Listing<X> {...}`
- amendment of `property: Listing<X>`
