d94ddbed2c 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.

2787e3cd65 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.

18b4e36df1 Move check for named params in fcall optimization earlier 
I don't think this is strictly necessary, but I think it makes
sense to check this before interpreting opline->op2.num as an
argument number.

This also adds one more has_known_send_mode() check that I had
missed before.
