1.0.46.44: room: Fix map-stack-references for stack-grows-upward systems.

  * SAP+ is (function (system-area-pointer integer) (values
system-area-pointer)).

  * SAP- is (function (system-area-pointer system-area-pointer) (values
integer)).

  * When negating the delta in a SAP+ operation, don't use SAP-.
Instead, negate the offset.  Otherwise, you get a WARNING for passing an
integer where a system-area-pointer is expected.
