MN10300: Fix register-postinc addressing misalignment handling
David Howells authored

Fix misalignment handling of operands with register postincrement addressing.
The flag to indicate that postincrement is required should not be interpreted
as an specification of a value to be added to the address.

Also add BUGs to catch unimplemented parameter markings in the opcodes table.
