Message:

Update. We need to use two separate arrays: one for the heap and one for
the kimg. The size of a heap entry is configurable, but that of the kimg
is not (fixed by mcmodel).

As a result, we also need to use two XPTRs: XPTR_HEAP and XPTR_KIMG. For
now we only declare XPTR_KIMG, and are not using it yet.
