Fix RC1 assumption for typed properties with __get 
Unsetting typed properties resorts back to __get which may have RC1.

Closes GH-10833

Fix updating SSA object type for *_ASSIGN_OP (#10458) 
The code fetched the class entry into ce for objects and static
properties. However, when the actual update needs to take place (when
result_def exists), the class entry in ce was reset to NULL. So the SSA
object type update never happened. Fetch the class entry in the
result_def>=0 case instead after the reset of ce to NULL.

Fix incorrect check condition in type inference (#10425) 
The "nothing to do" case would never be hit because the switch block
would execute if the opcode is ZEND_ASSIGN_STATIC_PROP_OP,
not ZEND_ASSIGN_STATIC_PROP. This meant that we were falling through to
the else block. Fix this by correcting the check condition.

567213c32a Drop range inference for IS_NULL/IS_FALSE/IS_TRUE. 
These values not always converted to IS_LONG (e.g. by -- and ++) and
this leads to incorrect range inferene and later to incorrect JIT code
generation.

Convert iterable into an internal alias for Traversable|array (#7309) 
This does a compile time transformation of ``iterable`` into ``Traversable|array`` which simplifies some of the LSP variance handling.

The arginfo generation script from stubs is updated to produce a union type when it encounters the type ``iterable``
Extension functions which do not regenerate the arginfo, or write them manually are still supported by mimicking the compile time transformation while registering the function.

Type Reflection is preserved for single ``iterable`` (and ``?iterable``) to produce a ReflectionNamedType with name ``iterable``, however usage of ``iterable`` in union types will be converted to ``array|Traversable``

This is unlikely to matter in practice (due to short lifetime),
but necessary to satisfy the SSA integrity check.

df4c27642e Check opcode rather than result_type for R/IS type inference 
We may sometimes create FETCH_*_R opcodes with VAR type (e.g. if a
FUNC_ARG opcode is converted to BP_VAR_R fetch kind). Make sure we
don't infer overly conservative types in that case.
