Amara Emerson 5b2864cb25 [GlobalISel][AArch64] Allow CallLowering to handle types which are normally
required to be passed as different register types. E.g. <2 x i16> may need to
be passed as a larger <2 x i32> type, so formal arg lowering needs to be able
truncate it back. Likewise, when dealing with returns of these types, they need
to be widened in the appropriate way back.
