On ARM NEON, VAND with immediate (16/32 bits) is an alias to VBIC ~imm with
the same type size. Adding that logic to the parser, and generating VBIC
instructions from VAND asm files.
This patch also fixes the validation routines for NEON splat immediates which
were wrong.
Fixes PR20702.

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:

Use the new TwoOperandAliasConstraint to handle lots of the two-operand aliases
for NEON instructions. There's still more to go, but this is a good chunk of
them.

We could be more aggressive about making this work for a larger range of constants,
but this seems like a good start.
