This is a new case that comes up with `InlineArray`, since an `InlineArray` with unknown count but known trivial element type is trivial but still address-only due to its unknown size. We are inconsistent about whether we emit formal copies or not of these values; they should generally be unnecessary as long as the memory location of a value is sufficiently long-lived, but the SIL verifier still reasonably considers a `[take]` as an invalidation of the memory, even though at runtime a take is a no-op. Since the take is unnecessary, we can just not take when we copy out of a trivial address location. Fixes #84141 | rdar://160007939.
