[Gc] Partially scanning a VM's call stack

Guile's new VM uses an alternate stack for bytecode that's evaluated.
As with the C stack, the GC should not scan the stack below its current
bottom; failing to do so may lead to excess data retention.

What's the best way to handle this?  Are there other options than
zeroing the stack bottom once in a while?
