Merge branch 'PHP-7.3' into PHP-7.4

* PHP-7.3:
Fix bug #76047

Set opcache.optimization_level=0 in test

Otherwise opcache "inlines" the function, which causes a minor
difference in destruction behavior.

Test fixes

Fixed bug #78973

Save opline in leave helper to correctly handle destructor calls
during CV freeing (or other leave freeing).
