Stopped GCC warning about unused variables
...
We detect real unused variables from the occam program ourselves, but we don't want GCC warnings for all the unused _sizes variables and so on

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.

I still need to do a little more, however, to pass my more elaborate examples in the test file.

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

Fixed the constant folding to use a type for Int based on the compilation target rather than just assuming Int32
...
However, it is possible that there will still be a problem if the C and C++ compiler have different int sizes, because the constant folding has to know the type at compile time, and thus we have to arbitrarily choose to use the C version. In future, we could perhaps swap all Ints for the appropriate substiution (e.g. Int64) at run-time, based on the flags and prior knowledge about C/C++ int sizes

Defeated the GCC optimiser, to get a decent estimate of how slow multiplication is

Had a go at implementing multiply overflow checking (with a single division, and pre-checks)
...
I also added an occam testcase to help time the different between * and TIMES. But gcc optimises out the loop with TIMES under -O2, and with -O0 there is a factor of four difference.
