Summary: DateTime::createFromFormat returns static type

This is indeed an intended big fix. As this change doesn't violate LSP (the inherited child
class still follows the is_a relationship with DateTime), how does it cause a problem in your
situation?

Description:
------------
I don't know if this is actually a bug or intended behavior or undefined behavior. However,
since it's been consistent up to 8.0.0beta1, I thought I'd report the change.

DateTime::createFromFormat() used to always return a DateTime instance if called from a class that
extended DateTime and wrapped createFromFormat().
Now, it is returning the static type. In this example,that is an ExtendsDateTime instance.

Looking, I see a very old bug that suggests this was supposed to be the fixed behavior, but clearly
wasn't. We have some low level framework behavior keyed off the type of instance constructed,
so we'd like to make sure this is the intended switch for PHP 8.
