4527 - reading commandline arguments

The new example ex9 doesn't yet work natively.

In the process I've emulated the kernel's role in providing args, implemented
a couple of instructions acting on 8-bit operands (useful for ASCII string
operations), and begun the start of the standard library (ascii_length
is the same as strlen).

At the level of SubX we're just only going to support ASCII.
