Matt Arsenault 0c52bece01 AMDGPU: Fix unnecessary ands when packing f16 vectors 
computeKnownBits didn't handle fp_to_fp16 to report
the high bits as 0. ARM maps the generic node to an instruction
that does not modify the high bits of the register, so introduce
a target node where the high bits are known 0.
