Implement shiftLInteger and shiftRInteger
Currently shift for Integer (in Data.Bits) is defined in terms of (*), div and ^.
Instead, integer-* should export shiftLInteger and shiftRInteger, which can be more efficient.
We should do this after the builtin-primop/FFI-imported-primop stuff is worked out, so that we can use a suitable GMP function for it.
