a4fa00ead3 Reuse wrong string offset logic in jit 
JIT contains a copy of this function that effectively only differs
by fetching current_execute_data from EG. We can do that in the VM
version as well, as this is just used to throw an error.

Export the VM function and reuse it in JIT.

770879702a Fix JIT typed property inc/dec 
This was leaking memory for pre-inc/dec of a refcounted typed
property if the result was not used.

The code to do this was unnecessarily complicated, we can base
this on the zend_jit_inc/dec_typed_prop() helper and copy to the
result afterwards.

e7663785a7 Handle undef value in assign_dim jit 
We should report the undefined variable here and convert it to
null. Passing on undef is particularly insidious here, because
a write_dimension handler may insert it into a hash table
(observed with WeakMap).

a3f5b11994 Sync JIT overloaded assign/inc/dec overloaded property

a190c7fdb7 Sync JIT zend_check_string_offset()

warning during conversion.

6780aaa532 Implement readonly properties 
Add support for readonly properties, for which only a single
initializing assignment from the declaring scope is allowed.

RFC: https://wiki.php.net/rfc/readonly_properties_v2

052af90b86 Deprecate autovivification on false 
Deprecate automatically converting "false" into an empty array
on write operands. Autovivification continues to be supported
for "null" values, as well as undefined/uninitialized values.

RFC: https://wiki.php.net/rfc/autovivification_false

Closes GH-7131.
