Avoid useless store and checks in xlat_table.

Improved hash copying

Replace ZEND_ACC_ANON_BOUND, ZEND_ACC_UNRESOLVED_PARENT and ZEND_ACC_UNRESOLVED_INTERFACES with single ZEND_ACC_LINKED.

Removed incorrect efree() (run_time_cache(s) are usually allocated in CG(arena)).

Keep information about unresolved parent class in zend_class_entry->parent_name

Keep information about unresolved interfaces in zend_class_entry->interface_names.
Move interface implementation code into ZEND_DECLARE_*CLASS opcodes.
Remove ZEND_ADD_INTERFACE and ZEND_VER

Keep information about unresolved interfaces in zend_class_entry->interface_names.
Move interface implementation code into ZEND_DECLARE_*CLASS opcodes.
Remove ZEND_ADD_INTERFACE and ZEND_VERIFY_ABSTRACT_CLASS opcodes.

Replace zend_class_entry->traits by persistent zend_class_entry->trait_names.
Move trait binding code into ZEND_DECLARE_*CLASS opcodes.
Remove ZEND_ADD_TRIAIT and ZEND_BIND_TRAITS opcodes.

Use zend_class_entry/zend_function type names instead of _zend_class_entry/_zend_function tags.

Changed structure of zend_class_entry.trait_aliases and zend_class_entry.trait_precedences to avoid keeping "intermediate" trait references, that are used only during inheritance.

Eliminated REFCOUNTED checks on persistent constant operands in SEND_VAL[_EX] and QM_ASSIGN.

Lazy function copying from op_cache SHM into process memory

Fixed bug #76509

In PHP static properties are shared between inheriting classes,
unless they are explicitly overwritten. However, because this
functionality was implemented using reference, it was possible
to break the implementation by reassigning the static property
reference.

This is fixed by switching the implementation from using references
to using INDIRECTs, which cannot be affected by userland code.

Fixed HashTable load factor

Use zend_string_release_ex() instread of zend_string_release() in places, where we sure about string persistence.

Changed worst HashTable load factor from 1.0 to 0.5

Fixed use-after-free.
