This fixes ticket #47 from Trac, which explains how using a dependency graph for passes was a bit too over the top, and led to unexpected results. Under the "new" (the original!) system, the pass list is used as-is, but the dependencies are checked to make sure the pass list order isn't wrong. In future we should also add back running the properties at the appropriate point (currently disabled).
Now that I have begun moving all the _sizes stuff forward into proper compiler passes, much of the code for handling arrays in the backends is going to become redundant:
- The tockArrayView class should eventually disappear; now that _sizes are pulled forward, there's no advantage of having this extra class (compared to just doing C and C++ arrays in the same, C-based, style)
- The declaration and use of the _sizes array everywhere should go, now that it is inserted in an earlier pass
I haven't removed as much as I should from the C backend; I am wary to touch it when Adam is about to move it over to the new CIF anyway
