Alexey Bader 9263931fcc [SYCL] Assume SYCL device functions are convergent
SYCL device compiler (similar to other SPMD compilers) assumes that
functions are convergent by default to avoid invalid transformations.
This attribute can be removed if compiler can prove that function does
not have convergent operations.
