- Refactoring dtor sanitizing emission order
- support for virtual functions & virtual bases WIP
- Repress dtor aliasing when sanitizing in dtor
- CFE test for dtor aliasing, and repression of aliasing in dtor code generation.
- More complex testing for destruction order.
- Poison trivial members one-by-one.
- Poisoning on field-by-field basis, with collective poisoning of trivial members when possible.
- Cleaned up implementation of calculating region to poison in dtor.
- Checking for existence of a single trivial field.
