  1. rdrand: Avoid assuming usize is the native word size. 

    `x86_64-unknown-linux-gnux32` has target_pointer_width = "32", so
usize is 32-bits. In this case, we were throwing away half of each
RDRAND result and doing twice as many RDRAND invocations as
necessary. This wasn't noticed because `as` silently does a lossy
conversion.
