Reviewed by Mike Wyrzykowski.

The type declaration for `<<` and `>>` was wrong: it specified that both lhs and
rhs, should have the same type, either i32, u32 or a vector of either. However,
the spec[1] specifies that rhs must always be u32, and only lhs can be i32 (or u32).
This also required changed the constant function, as the BINARY_OPERATOR macro assumes
that both arguments will have the same type.
