When assigning to an attribute of an object with
Py_TPFLAGS_MANAGED_DICTthat lacked either a values array or a__dict__,we currently create a
__dict__.This PR allocates a values array instead.
In an ideal world, we would allocate the values array when we allocate the object.
But that will require better integration of the VM, allocator and GC. So that's for another PR in the future.
__dict__s #106485
