Add Int32/Float64 nodes for: * Subtract * Multiply * Divide and additionally Int32 nodes for * BitwiseOr/And/Xor * ShiftLeft/Right/RightLogical The latter ones don't have Float64 equivalents since they're implicitly Int32 operations. In the future we'll add support for Number feedback by adding Float64-to-Int32 conversions and using the Int32 nodes. The divide node does an Int32 division and deopts if there's a remainder to the division -- we may want to make it output a Float64 instead if we think that's more likely in real-world code. There's also no peephole optimisations for constant operations, which would generate much better code, especially for shifts.
