Max Moiseev 54e5f5d741 Handling the differences in << and >> for Swift 3 vs Swift 4 ...

In Swift 3 shifts used to be defined on the concrete integer types, so
the right-hand-side value in the shift expression could define a type
for the result, as in `1 << i32` would have the type Int32. Swift 4
makes shift operators heterogeneous, so now `1 << i32` will result in an
Int, according to the type of the left-hand-side value, which gets a
default type for integer literals.
