Question about shuffle

Does a user need to implement OpenCL shuffle in SYCL ?

@jinz2014 have you considered vec swizzles (4.10.2.3 from spec)? They seem to have the same purpose. The only downside I see is that mask must be known at compile time.

Otherwise, you're right, there's no shuffle builtin in SYCL.
