6041 - array indexing starting to work

And we're using it now in factorial.mu!

In the process I had to fix a couple of bugs in pointer dereferencing.

There are still some limitations:
a) Indexing by a literal doesn't work yet.
b) Only arrays of ints supported so far.

Looking ahead, I'm not sure how I can support indexing arrays by non-literals
(variables in registers) unless the element size is a power of 2.
