Fix ISeq dump / load in array cases

We need to dump relative offsets for inline storage entries so that
loading iseqs as an array works as well.  This commit also has some
minor refactoring to make computing relative ISE information easier.

This should fix the iseq dump / load as array tests we're seeing fail in
CI.
