Carbon.h now compiles without error!

All 14 errors were the result of two Type predicates (isArithmeticType
and isScalarType) not allowing enums. Note: this could have been avoided by rigorously using
isIntegerType. For efficiency, I decided not to have predicates use predicates.

Still more work to do, however this is a nice milestone considering how much "work" is being done...
