1. Simple type const 2. Inherent associated type const 3. Trait associated type const

The correct size for `Layout` of a scalable vector ought to include the number of vectors, otherwise we generate `memcpy` that do not copy the entire vector and things like that.

rustc typically uses a return area pointer if the size of a return value is larger than two pointers, except for SIMD vectors and now scalable vectors. Given the previous commit, scalable types are more likely to trigger this conditional than previously. This is already tested in the output of the `codegen-llvm/scalable-vectors/tuple-intrinsics.rs` test.
