Fix output constraints for bn_umul_hilo().
When bn_umul_hilo() is implemented using an instruction pair, mark the
first output with a constraint that prevents the output from overlapping
with the inputs ("&"). Otherwise the first instruction can overwrite the
inputs, which then results in the second instruction producing incorrect
value.
