Exposes barrier as a free function, aligned with group_barrier from SYCL 2020 provisional. Naming is aligned with the existing DPC++ group algorithms, hence barrier in place of group_barrier. Signed-off-by: John Pennycook <john.pennycook@intel.com>

Please fix test/build failures. |
I don't think they're related to this PR. The same test is failing across multiple PRs. |
Even better! |

A set of llvm.vector.reduce.* intrinsics doesn't have straight forward operation equivalent on the SPIRV side. The easiest solution to this problem is to use scalar operation on each pair of vector elements and repeat until there is only one value. Original commit: KhronosGroup/SPIRV-LLVM-Translator@fe088cd
