Now this is no longer space-constrained (the location union is two pointers
in size anyway), so this can just be an "int" like regnums are elsewhere.

Hmm, I think we recently had the discussion that *any* values should allow
using an offset.  The comment should probably reflect this.


Otherwise, this looks good to me.
