Merge of the nonstrict-ops branch:
- Most RTL operators now evaluate to Some Vundef instead of None
when undefined behavior occurs.
- More aggressive instruction selection.
- "Bertotization" of pattern-matchings now implemented by a proper preprocessor.
- Cast optimization moved to cfrontend/Cminorgen; removed backend/CastOptim.
