5156626ab0 Remove the identifyParProcs pass. 
All it did was to make a list of the Procs generated by parsToProcs, so
parsToProcs may as well just do the same job itself.

The reason I'd made it a separate pass originally was that I wanted to
optimise out the wrapper when the child of a Par was already a ProcCall.
That optimisation isn't going to be possible any more with the new CCSP,
since wrappers have to fetch their arguments in a different way from
ordinary Procs.

08d02bfb17 Changed the behaviour of assignment for records 
Previously, assignments of records were directly flattened into assignment of each of the fields.  Now, we instead generate a copy_<recordname> inline procedure for each record definition, and compile code that uses that (for C++, we could even make this an operator= implementation later on).  This allows us to re-use the proc later in the C/C++ backends if needed.

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

9cd2da3b0e A large change to alter RainUsageCheck to use the code in UsageCheck 
Previously there was near-duplicate code in UsageCheck adapted from RainUsageCheck.  This patch removed the duplicate code on the RainUsageCheck side, and resulting in changing the rest of the module (and its corresponding test module) to use the new UsageCheck version of the code.  The net effect is to almost completely unify the passes in RainUsageCheck (which aren't really Rain-specific anyway), UsageCheck and ArrayUsageCheck.
