Some time ago, there was a thread in which someone explained (I think
Robert Dewar) that 'aliased' does not provide any help to the compiler
regarding alias detection, register allocation etc. because the
compiler has to be able to determine this kind of information anyway
if an Address attribute is used.

So in code-generation terms, 'aliased' is a no-op.
