Fix SEND_USER with ref arg

Even though the input is not a reference (or not treated as such),
we still need to create a reference to satisfy the function
signature. Various code relies on reference arguments actually
being references. In this particular case, it would result in
a JIT crash.

The zend_call_function() implementation already handled this
correctly.

Avoid use after free in internal prop type verification

This issue only applies to debug builds: read_property can free
the object, but we'd try to check the object handlers afterwards.

This issue only applies to debug builds: read_property can free
the object, but we'd try to check the object handlers afterwards.
Rewrite the check in a way that only accessed the object before
the read_property call.

Fix ASSIGN_DIM to NEXT with rc=1 reference value

The reference wrapper was destroyed while value still pointed into
it and was later used to assign the ASSIGN_DIM return value. This
could be fixed either by moving the return value assignment earlier,
or by working with the value that has been stored in the array.
I'm going with the latter here, because that matches what the
non-NEXT codepath does via assign_to_variable more closely.

Preload unlinked classes, remove preload autoload (#7311)

Currently, classes that can't be linked get moved back into the original script
and are not preloaded. As such classes may be referenced from functions that
did get preloaded, there is a preload autoload mechanism to load them at
runtime.

Since PHP 8.1, we can safely preload unlinked classes, which will then go
through usual lazy loading. This means that we no longer need the preload
autoload mechanism. However, we need to be careful not to modify any hash
table buckets in-place, and should create new buckets for lazy loaded classes.
