I assume you mean heap-ivectors, as created by MAKE-HEAP-IVECTOR.  (An ivector is a type of uvector that contains only immediate data.)  These heap-ivectors reside in memory allocated via malloc, so any tools you have that can tell you about the malloc heap would apply.

I don't think there is anything specifically for that.  Presumably something could walk ccl::*heap-ivectors* and figure something out...

[hacks for a while]

Update to r13533 and try CCL::HEAP-IVECTOR-UTILIZATION.
