[PATCH] D79283: [PowerPC] Add missing handling for half precision

> This is missing from the SystemZ back end

I don't think this change is right for SystemZ.  This would change the ABI for single-element vector types.   According to our ABI we **want** to pass those in vector registers, which requires widening to the full-width vector type.   With your change, common code would instead scalarize to the scalar type, which means the parameter would be passed in GPRs instead.
