Nikita Popov 2e9e706a82 Fix throwing of yield from related exceptions into generator
Use the general zend_generator_throw_exception() helper for this.
Otherwise we don't handle the off-by-one opline correctly (should
we maybe just stop doing that?)

This is a followup to ad750c3bb6,
which fixed a different yield from exception handling problem that
happened to show up in the same test case from oss-fuzz #25321.
Now both issues should be fixed.
