This alters the lowering of G_COPYSIGN to support vector types. The general idea is that we just lower it to vector operations using and/or and a mask, which are now converted to a BIF/BIT/BSP. In the process the existing AArch64LegalizerInfo::legalizeFCopySign can be removed, replying on expanding the scalar versions to vector instead, which just needs a small adjustment to allow widening scalars to vectors.
