Renamed Main.oz into Compiler.oz.
Fixed a bug in the compiler due to the absence of RecordC.

To save heap space in static analysis, the compiler artificially
transforms "big" records into RecordC's with a restricted number
of features. This introduces RecordC's within the compiler. This
is currently a problem since RecordC's are not implemented yet.

This commit deactivates this "optimization" so that the compiler
can work even though RecordC's are not implemented yet.
