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.

Added error return to the checkInitVar function, and also changed it to use the new extended Set implementation, which in turn allowed me to fix the bug in the checkInitVar function (defVal is Everything, not the empty set)
