Andy McFadden 7a7ff44d3a Address region isolation, part 3 (of 3) ...

If an address resolves to a user label in an isolated region, we
don't want to use it.  However, we still want to try to match it
to a project/platform symbol.

For example, suppose the isolated code wants to reference address
$1C00, which is a memory-mapped I/O location in one area, but a
regular bunch of code in the other.  We don't want it to map to
the regular code, but we do want it to resolve to our table of
platform I/O addresses.

We now handle this correctly.  The regression test has been updated
to check this.  The current implementation does a linear scan through
the symbol table, but I'm hoping this is not a common situation.

The reference manual has been updated to describe the new feature.
