902d64390e Deprecate implicit dynamic properties 
Writing to a proprety that hasn't been declared is deprecated,
unless the class uses the #[AllowDynamicProperties] attribute or
defines __get()/__set().

3661c1932c Fix array cast type inference wrt packed arrays 
Use KEY_LONG instead of PACKED if it's possible for the array to
be empty. It won't be packed in that case.

Fixes oss-fuzz #39650.

5bf088f6eb Move TYPE_CHECK handling from sccp to inference 
The handling of TYPE_CHECK makes for an awkward special case,
because it is determined outside the usual SCCP framework. Instead
move the logic into type inference (to infer a more specific
may_be_true or may_be_false if possible). This will get picked up
by SCCP through the existing logic to make use of type and range
information.

However, this also requires us to make use of type info in
feasible edge marking, otherwise we would regress existing
optimization power.

for INIT_ARRAY and implements all this logic correctly.
