#5641: Fix HIP & CUDA MDRange reduce for sizeof(value_type) < sizeof(…
…int) (#5745) * Fix comment typo noticed in early analysis * Add test case * #5641: HIP: Fix MDRange parallel_reduce over values smaller than int * #5641 Cuda: Fix MDRange parallel_reduce over values smaller than int * Try to appease icpc's idiocy * Skip the test for OpenMPTarget backend, since it's broken * Sample bound values to test, rather than sweeping * Shrink largest bound value to avoid timeout * Report skipped in disabled CUDA extended lambda case * Fix skipping condition
