From now on, we always display the given object's type instead of just reporting "object".
Additionally, make the format of return type errors match the format of argument errors.
Closes GH-5625
Closes GH-5353. From now on, PHP will have reflection information
about default values of parameters of internal functions.

To explicitly indicate that objects are uncomparable. For now
this has no functional difference from the usual 1 return value,
but makes intent clearer.
Since `DateTimeZone` does not implement a `compare_objects` handler,
nor has any properties, two `DateTimeZone` instances always compare as
being equal, even if they designate totally different timezones. Even
worse, after calling `var_dump()` on these objects, the actual
comparison may yield a correct result.
We therefore introduce a `compare_objects` handlers, which prevents
different behavior before/after `var_dump()`, and which allows us to
clearly define the intended semantics.
We check that the given microsecond fraction is in the valid range
[0, 1000000[, and otherwise mark it as invalid. We also drop the
useless do loop; a plain block is sufficient here.
When getting the properties of a DatePeriod instance we have to retain
the proper classes, and when restoring a DatePeriod instance we have to
cater to DateTimeImmutable instances as well.
