This goes in the reverse direction of 4463acb951.
After looking around a bit, it seems that we already check for
Z_ISERROR_P() on the get_property_ptr_ptr return value in other places.
So do this in zend_fetch_property_address() as well, and also make
sure that EG(error_zval) is indeed returned on exception in
get_property_ptr_ptr.
In particular, this fixes the duplicate exceptions that we used to
get because first get_property_ptr_ptr threw one and then
read_property throws the same exception again.
Relying on setting ERROR if an exception happened during the
property address fetch is both a bit fragile and may pessimize
other codepaths that will check for exceptions in the VM. Adding
an extra exception check instead, which should also allow us to
drop the use of ERROR in this area in master.
This is a fix for symfony/symfony#32995.
The behavior is:
* Throwing exception when loading parent/interface is allowed
(and we will also throw one if the class is simply not found).
* If this happens, the bucket key for the class is reset, so
it's possibly to try registering the same class again.
* However, if the class has already been used due to a variance
obligation, the exception is upgraded to a fatal error, as we
cannot safely unregister the class stub anymore.

And convert some object to string conversion related recoverable
fatal errors into Error exceptions.
Improve exception safety of internal code performing string
conversions.
This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines in all
*.phpt sections.
According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.
C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."
Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

Instead overload get_properties_for for a few specific cases such
as array casts. This resolves the issue where ArrayObject
get_properties may violate engine invariants in some cases.
This seems to be a simple oversight, where we did not enable
exceptions. Other constexpr conditions already throw, so there is
no particular reason to stick to a fatal error here.
When including files in PHP tests a good practice so far has been to use
the *.inc extension. This patch renames few *.p5c files that are
included in phpt files.
In PHP static properties are shared between inheriting classes,
unless they are explicitly overwritten. However, because this
functionality was implemented using reference, it was possible
to break the implementation by reassigning the static property
reference.
This is fixed by switching the implementation from using references
to using INDIRECTs, which cannot be affected by userland code.
PHP requires integer typehints to be written "int" and does not
allow "integer" as an alias. This changes type error messages to
match the actual type name and avoids confusing messages like
"must be of the type integer, integer given".
