Comparison
A range of comparison intrinsics are provided. If the comparison is true for a lane, the
result in that lane is all bits set to one. If the comparison is false for a lane, all bits are
set to zero. The return type is an unsigned integer type. This means that you can use the
result of a comparison as the first argument for the vbsl intrinsics.
