e08aac59d3 Move Retypes checking from the occam parser into a pass.
This also fixes a bug in the original algorithm: it used to let you retype
[]INT to BYTE.

7f6cb6e0c3 Evaluate "(MOSTNEG INT) \ -1" correctly when evaluating constants.
This actually crashes older versions of GHC:
  Prelude Data.Int> (minBound :: Int32) `div` (-1)
  Floating point exception

b1416bb0cf Change A.Dimension to take an Expression, not an Int.
This touches an awful lot of code, but cgtest07/17 (arrays and retyping) pass.

This is useful because there are going to be places in the future where we'll
want to represent dimensions that are known at runtime but not at compile time
-- for example, mobile allocations, or dynamically-sized arrays. It simplifies
the code in a number of places.

However, we do now need to be careful that expressions containing variables do
not leak into the State, since they won't be affected by later passes.

Two caveats (marked as FIXMEs in the source):

- Retypes checking in the occam parser is disabled, since the plan is to move
  it out to a pass anyway.
- There's some (now very obvious) duplication, particularly in the backend, of
  bits of code that construct expressions for the total size of an array
  (either in bytes or elements); this should be moved to a couple of helper
  functions that everything can use.

6df110dce4 Wrap QuickCheck tests into HUnit tests.
This means all the tests now get run as part of one list, and HUnit keeps track
of the number of failures for us. (The reason I was doing this was so that
tocktest will exit non-zero on QuickCheck test failure too.)

As part of this, I've reworked TestMain's main function quite a bit. It'll now
filter QuickCheck tests into response to options too.

2f7539bcdb Convert the C backend to the new CIF API (mostly).
Most of this is mechanical: changing function names, and carrying the "wptr"
argument around. I've made the code for computing Expressions from Structureds
a bit more generic too.

The only complex bit is the handling of PAR processes, which I'm not very happy
with at the moment; they used to use the normal C calling convention, but now
you need to pack the arguments into the workspace. I'm handling this at the
moment by generating wrapper functions that do the unpacking, but it would be
better in the future to make the wrapper PROCs that we already generate have
the right interface.

This won't work for programs that use any of the top-level channels yet, since
there are no handlers for them.

8f2575819b Initial implementation of the occam-pi preprocessor.
This implements #DEFINE, #UNDEF, #IF, #ELSE and #ENDIF, macro expansion with
##, and TRUE, FALSE, AND, OR, NOT and DEFINED within #IF expressions, with the
same semantics as occ21.

The macro COMPILER.TOCK is always defined by default, so you can now say things
like "#IF NOT DEFINED (COMPILER.TOCK) ... #ENDIF".

fa1e9a6a08 Rearranged FlowGraph and fixed the tests
Previously, most of the flow-graph building functions were inside the where clause of buildFlowGraph.  They have been moved to the top-level (with only a few small changes to make this possible - the main one being to store the labelling functions in a reader monad, which only required changing a couple of lines) and used by an additional buildFlowGraphP function, that is now used by the tests to make them work simply.  None of the new top-level functions except buildFlowGraphP are exported from FlowGraph.

acd57d74de Changed the A.Structured type to be parameterised
This patch is actually an amalgam of multiple (already large) patches.  Those patches conflicted (parameterised Structured vs. changes to usage checking and FlowGraph) and encountered a nasty bug in darcs 1 involving exponential time (see http://wiki.darcs.net/DarcsWiki/ConflictsFAQ for more details).  Reasoning that half an hour (of 100% CPU use) was too long to apply patches, I opted to re-record the parameterised Structured changes as this new large patch.  Here are the commit messages originally used for the patches (which, as mentioned, were already large patches):

A gigantic patch switching all the non-test modules over to using parameterised A.Structured
Changed the FlowGraph module again to handle any sort of Structured you want to pass to it (mainly for testing)
A further gigantic patch changing all the tests to work with the new parameterised Structured
Fixed a nasty bug involving functions being named incorrectly inside transformInputCase
Added a hand-written instance of Data for Structured that allows us to use ext1M properly
Fixed a few warnings in the code
