Currently, glue functions take a pointer to a value. This means we're spilling all temporary boxes and unique pointers to the stack just in order to drop them. This is rather wasteful. If we know the type (which we do for all immediates -- generic values are never treated as immediate), we should be able to take and drop without spilling.

This way, it can be used to drop values without first spilling them.
