operator% is not available for sycl::vec in some cases

[kopylovanat]

There is

operator&(const vec& lhs, const vec& rhs) 
operator&(const vec& lhs, const DataT& rhs) 
operator&(const DataT& lhs, const vec& rhs)

in 4.14.2.1. Vec interface , but they are not available for swizzled vec and the last one not available for regular vec also.

To Reproduce

#include <sycl.hpp>

int main() {

  sycl::vec<int, 2> testVec1(3);
  sycl::vec<int, 2> testVec2(2);
  int v = 5;

  sycl::vec<int, 2> resVec;
  resVec = v % testVec2;

  resVec = testVec1.template swizzle<sycl::elem::s0, sycl::elem::s1>() % testVec2.template swizzle<sycl::elem::s0, sycl::elem::s1>();
  resVec = testVec1.template swizzle<sycl::elem::s0, sycl::elem::s1>() % v;
  resVec = testVec1.template swizzle<sycl::elem::s0, sycl::elem::s1>() % testVec2;
  resVec = v % testVec2.template swizzle<sycl::elem::s0, sycl::elem::s1>();

clang++ -fsycl ./sample_vec_subscript.cpp -o sample

Output:

./sample_vec_subscript.cpp:7:58: error: type 'Swizzle<1>' (aka 'SwizzleOp<sycl::vec<int, 2>, GetOp<int>, GetOp<int>, sycl::detail::GetOp, 1>') does not provide a subscript operator
