Add some testcases for usage-checking on user-defined array types.
...
These were based on KRoC bug #194 , submitted by Jonathan May.

Fixed inferTypes so that it again handles Specifications in Structured ExpressionList in function definitions

Changed the abbreviation checking so that it doesn't check nonce names
...
When we pull up names (which happens before abbreviation checking), we create a lot of nonces with greater scope than the original variables. When we go to abbreviation check this, we therefore set off lots of false alarms about originally safe code. So to fix this, the easiest method seems to be turning off checking on all the names introduced by the compiler.

Removed obsolete conditions from the valid set as we search for constraints
...
Previously, conditions from IF branches were being retained even after the end of the whole IF. Now I use the just-added information from the flow graph as to when those conditions are no longer applicable.
