Opcode accesses are now marked debugger_access. This is important with the recent

changes to automatically call the read handler if the opcode base cannot be
found.

Changed logging for non-RAM opcode bases so that it does not output in the case
of debugger_access being set.

Fixed logic for deriving direct ranges so that it uses the non-watchpoint-
infected tables for its lookups.
