Update on the Mu computer's memory-safe language

Mu just got its first couple of non-integer types: addresses and arrays. As a result, the factorial app can finally run its tests based on command-line args.

http://akkartik.github.io/mu/html/apps/factorial.mu.html

Addresses are accessed using a '*' operator. Arrays are accessed using an index instruction that takes an address (addr array T) and returns an address (addr T).

Literal indexes aren't supported yet.

Open question: indexing arrays of non-power-of-2 element sizes.
