Function maskerad_memory_allocators::utils::bitpack_type_description_ptr

pub fn bitpack_type_description_ptr(
    p: *const TypeDescription, 
    is_done: bool
) -> usize

Encode whether the object (described by a TypeDescription) has been initialized in the StackAllocator in the low bit of the TypeDescription pointer.

This is necessary in order to properly do cleanup if a panic occurs during an initializer.
