Method materialize_localsplus

crates/vm/src/frame.rs:777–779

Migrate data-stack-backed storage to the heap, preserving all values, and return the data stack base pointer for `DataStack::pop()`. Returns `None` if already heap-backed. # Safety Caller must ensure the frame is not executing and the returned pointer is passed to `VirtualMachine::datastack_pop()`.

    /// pointer is passed to `VirtualMachine::datastack_pop()`.

    /// Clear evaluation stack and state-owned cell/free references.
    /// For full local/cell cleanup, call `clear_locals_and_stack()`.
