Correct handling of no-op .ORG statements

Browse Source 
These were being overlooked because they didn't actually cause
anything to happen (a no-op .ORG sets the address to what it would
already have been).  The assembly source generator works in a way
that causes them to be skipped, so everybody was happy.

This seemed like the sort of thing that was likely to cause problems
down the road, however, so we now split regions correctly when a
no-op .ORG is encountered.  This affects the uncategorized data
analyzer and selection grouping.

This changed the behavior of the 2004-numeric-types test, which was
visibly weird in the UI but generated correct output.

Added the 2024-ui-edge-cases test to provide a place to exercise
edge cases when testing the UI by hand.  It has some value for the
automated regression test, so it's included there.

Also, changed the AddressMapEntry objects to be immutable.  This
is handy when passing lists of them around.
