p. ZEND_EXT_BEGIN_FCALL is emitted after arguments are sent, this means
that handlers may access arguments.
q. ZEND_COMPILE_IGNORE_USER_FUNCTIONS and ZEND_COMPILE_IGNORE_INTERNAL_FUNCTIONS
are respected by zend_get_call_op such that when set, the only possible
call opcodes are ZEND_DO_FCALL and ZEND_DO_FCALL_BY_NAME, previously they
were ignored by zend_get_call_op.
