The ARM NEON vector compare instructions take three arguments. However, the
assembler should also accept a two arg form, as the docuemntation specifies that
the first (destination) register is optional.
This patch uses TwoOperandAliasConstraint to add the two argument form.
It also fixes an 80-column formatting problem in:
