Conversion support clean-up.
Got rid of the ConversionResult class and simplified both Types.isAssignable/Types.isConvertible. Now an unchecked exception is used in order to propagate a detailed diagnostic message about what went wrong during a conversion --- this is more in sync with the rest of the javac code.
