Make Core.Float a class. Add missing builtins for float support. (#5932)

Browse Source 
Add missing builtins for float compound assignment, for building a
FloatType, and for converting a float literal to FloatType. Switch
`Core.Float` to being a class and add impls for the various
floating-point operators.
