Started simplifying some of the C backend in light of the new changes, and made a few fixes
...
The first few cgtests (at least) now pass with the new system in the C backend.

Fiddled with the new variable stuff in the C backend, and now variable subscripts seem to work

Quickly implemented the first version of a revamp of the genVariable code in the C backend
...
Surprisingly, the generated code seems to be compiled by GCC without warnings. Array subscripts are currently unimplemented (a star, i.e. equivalent of subscript 0) is used wherever there should be a subscript.
The new mechanism is based on working out the C type of the original variable/abbrev-mode, the C type of the desired variable/abbrev-mode, and works out how many *s or &s to insert to coerce it to the right type.

Bashed the backend until it works with the new mobility passes (standard occam may be broken though)

Removed C++CSP's mobile stuff so that I only have one unified system to deal with for now

Corrected some problems caused by moving the direction specifiers up to the whole array (the array wasn't then being pulled up)

Implemented recursive procs

This works fine in the C++ backend, not tested with the C backend yet

Fixed a bug involving abbreviation of arrays of channels into arrays of channel-ends in the C++ backend
...
The array for the channel-ends was not being allocated storage, so the array (a pointer to some random location) was being written to and causing a seg-fault

Implemented all but one (RAN) of the intrinsic functions in appendix N by mapping them directly to the C versions

1410e80fb1
Added support for intrinsic functions with multiple return values
...
Previously, such a function was an IntrinsicFunctionCall inside one expression of an ExpressionList, which the type-checker rejected. I've had to add a new constructor to ExpressionList, and I've quickly hacked together the line in the C backend to make it work -- but it does seem to work.

Tweaked the C and C++ backends to take the replacement for Int from the TypeSizes module rather than calculate it locally

Fixed all the tests to reflect the new channel-end system, such that they all pass again

Made the size of INT vary between 16-,32- and 64-bit platforms
...
Fixes #37 . The change itself was very easy, but the main problem was to then go and change everything in GenerateCTest that had been written using A.Int as a test type.
