Map vector types to arrays and pass them by value
This PR maps vector types to arrays and passes them by value (that is, they are passed to C as `[T; N]`. This already allows defining them as a blacklisted opaque type, such that the user can provide its own definition from e.g. `std::arch`.
A subsequent PR should map vector types to unit structs with a private member:
```rust
#[repr(align(16))] pub struct __m128([f32; 4]);
```
to make their alignment at least be correct. This should allow transmuting `std::arch` types to these types properly.
Once that is done, we probably want to detect the canonical vector types (e.g. `__m128`) and pull in the type from `std`/`core`::arch instead.
