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.

dfe9c2af19 Fix incorrect comparison in block optimization pass 
We're in the case of ZEND_JMPZ_EX or ZEND_JMPNZ_EX. The opcode gets
overwritten and only after the overwriting gets checked if we're in a
JMPZ or JMPNZ case. This results in a wrong optimization.

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.

dc5475c191 Save previous observer on the VM stack 
This avoids a possible significant performance penalty, when some leaf function was observed, deep in the stack.
As a side effect, we are not iterating over prev_execute_data anymore and thus, non-observed fake frames, possibly on stack, cannot have any impact on the observer anymore (especially within zend_observer_fcall_end_all).

Saving the previous observer happens now directly on the VM stack. If there is any observer, function frames are allocated an extra zval (the last temporary), which will, on observed frames, contain the previous observed frame address.

Add support for Disjoint Normal Form (DNF) types (#8725) 
RFC: https://wiki.php.net/rfc/dnf_types

This allows to combine union and intersection types together in the following form (A&B)|(X&Y)|T but not of the form (X|A)&(Y|B) or (X|A)&(Y|B)|T.

* Improve union type parsing
