Have constant folding be more flexible.
- Have Evaluate methods take as argument(s) and return value
instances of HConstant (instead of built-in 32- or 64-bit
integer values), to let the evaluated instruction choose
the type of the statically evaluated node; for instance,
art::HEqual::Evaluate shall return a HIntConstant
node (as implementation of a Boolean constant) whatever
the type of its inputs (a pair of HIntConstant or a pair
of HLongConstant).
- Split the evaluation job from the operation logic: the
former is addressed by Evaluate methods, while the latter
is done by a generic Compute method.
- Adress valid BinOp(int, long) and BinOp(long, int) cases.
- Add a constructor to art::HIntConstant to build an integer
constant from a `bool` value.
