This routine must be called
once all use of compiled quality expression identifiers (as generated by IRQ_COMP) has been
completed. All internal resources used by any such identifiers currently in use are released. Note, this
routine does not release the locators created by IRQ_NEW or IRQ_FIND. IRQ_RLSE must be called to
release these locators.
This routine attempts to execute even if STATUS is bad on entry, although no further error report will
be made if it subsequently fails under these circumstances.
