Though the spec doesn't say it, it might as well be worth also disallowing
shifts equal to the size of the quantity, as they just zero the value.

Or, at least, they should: some appear to be no-ops currently. As pointed out
by Thomas Kühne in digitalmars.D.learn (
http://lists.puremagic.com/pipermail/digitalmars-d-learn/2007-May/005040.html
), compile-time shifts should be done by ((shift >= x.sizeof * 8) ? 0 : shift)
instead of the current (shift % (x.sizeof * 8)).
