Split into real Debug and Release configurations and add some more flags.

- Release now uses all optimizations.
- Compiler warnings as errors.
- Link-time optimization.
- Static runtime linking.
- Ignore 64-bit unportability.
- Map Normal -> Debug for compatiblity with humans who are too lazy to migrate.
