Clean up art::HConstant predicates.

- Make the difference between arithmetic zero and zero-bit
  pattern non ambiguous.
- Introduce Boolean predicates in art::HIntConstant for when
  they are used as Booleans.
- Introduce aritmetic positive and negative zero predicates
  for floating-point constants.
