Yuta Saito e259a257e6 RedundantLoadElim: Fix invalid destructure_struct emission without aggressive reg2mem ...

The `shouldExpand` in `OptUtils.swift` was incorrectly returning `true`
unconditionally when `useAggressiveReg2MemForCodeSize` was disabled. The
expansion might be invalid for types with addr-only types and structs
with deinit, but we didn't check them before. This could lead to invalid
`destructure_struct` instructions without `drop_deinit` being emitted.
