SIMD Overlay: inline deprecated methods (#23250)
SIMD Overlay: inline deprecated methods (#23250)

On Swift 5, using the deprecated `SIMD.init(_ scalar: Scalar)` initialiser rather than `SIMD.init(repeating scalar: Scalar)` will cause the type to fail to be specialised, resulting in performance degradation. Mark this method and `static prefix func -` as `@_transparent` to ensure they are correctly specialised.
