ARC: Enforce function alignment at code emission time
Don't do this in the MachineFunctionInfo constructor. Also, ensure the
alignment rather than overwriting it outright. I vaguely remember
there was another place to enforce the target minimum alignment, but I
couldn't find it (it's there for instructions).
