This potentially saves a cache miss per scavenge.

Introduce snapshotting of thread's own stack

Introduce `StackSnapshot#` type and the `cloneMyStack#` primop, allowing
the user to reify the state of the calling thread's stack for later
inspection.

The stack snapshot is offline/cold, i.e. it isn't evaluated any further.

For technical details, please see note [Stack Cloning].

Introduce cloning of other threads' stacks

Introduce `cloneThreadStack` function, allowing threads to request
snapshots of other threads' stacks.

For technical details, please see note [Stack Cloning].

StackSnapshot#'s.
