Check signed right shift behaviour at compile time
We can use a test on a constant expression which should optimise away to
just the required version of the code, which means that on platforms
which perform sign-extension (pretty much everything current it seems)
we don't have to rely on the compiler optimising a portable idiom
correctly.
