Return the types for a coerce-and-expand operation.
The first type matches the memory layout of the data that's been added to this structure, including explicit [N x i8] arrays for any internal padding.
The second type removes any internal padding members and, if only one element remains, is simply that element type.

According to the target Swift ABI, should a value with this lowering be passed indirectly?
Note that this decision is based purely on the data layout of the value and does not consider whether the type is address-only, must be passed indirectly to match a function abstraction pattern, or anything else that is expected to be handled by high-level lowering.
| asReturnValue | - if true, answer whether it should be passed indirectly as a return value; if false, answer whether it should be passed indirectly as an argument |
