77be0c1137 Add some testcases for usage-checking on user-defined array types. 
These were based on KRoC bug #194, submitted by Jonathan May.

2ecd91e36f Changed the array usage checking to always include equations involving replicators 
This allows us to check situations like this:

PAR i = 0 FOR 10
  IF
    i = 0
      a[10] := 3
    TRUE
      a[i] := 3

Previously this would have been flagged unsafe (because 10 can overlap with 10 between the replicated branches).

But with this change, the equations on the replicators (including: i'>=i+1, i = 0, i' = 0) are included alongside 10=10, so there is no solution over all because the replicator equations prevent a solution (i.e. the 10 can't be used twice in parallel).

62a0873d3d Implement channel direction decorators. 
This is mostly straightforward: modify the parser to allow direction
decorators in the right places, and extend the type checker to match.
There's some slight awkwardness in that some of the Types functions
have to perform the same checks as the type checker (e.g. directing a
non-channel), so I've tidied up their error messages a bit.

At the backend, I've just added a little pass to strip out all the
DirectedVariables, since the other backend passes don't handle them
gracefully. From the occam/C point of view this is fine, but I'm not
sure if it's going to cause problems for C++.

6ee21f76c9 Initial work on supporting INITIAL and RESULT abbreviations. 
This fixes the AST, parser and typechecker, and adds a pass to
transform Result back into Abbrev, but doesn't transform Initial yet.
(It actually works for trivial stuff anyway, but it won't do the right
thing for complex types or PROC parameters.)

It appears (to me) to make sense to support INITIAL/RESULT reshaping
and retyping too, so this does.

Refs #42.
