Add zend_fetch_class_with_scope() which accepts a scope to use for
self/parent, and use that during constant expression evaluation.

Don't populate CE_CACHE during compilation

It's possible for CE_CACHE slots to be populated during compilation
(e.g. due to an early binding attempt). When opcache then persists
the class, it clears the CE_CACHE slot for the class name as declared,
but not for different spellings (that only differ in case). As such,
a pointer to the old, non-persistent class entry may be retained.

Fix this by not populating CE_CACHE if in_compilation is set.

Closes GH-7542.

Extract this into an zend_shutdown_executor_values() API function

Convert exception during inheritance to fatal error

Now that inheritance can throw deprecations again, these may be

Replay warnings during inheritance (#6928)

Since 3e6b447979a2b1f351faf40bee9c6cf7e362d85a it is again possible to have
warnings (deprecations) during inheritance, and more such functionality is
likely in the future. This is a problem, because such warnings will only be
shown on the first request if the opcache inheritance cache is used. This
currently causes test failures in --repeat builds.

Fix this by uplifting the error recording functionality from opcache to Zend,
and then using it to persist a warning trace in the inheritance cache, which
can then be used to replay the warnings on subsequent executions.
