This patch series is a rework of the patch series posted in August. https://patchwork.sourceware.org/project/gcc/list/?series=23045&state=%2A&archive=both
The series implements device-specific allocators and adds a low-latency allocator for both GPUs architectures. This time the omp_low_lat_mem_alloc does not work because the default traits are incompatible (GPU low-latency memory is not accessible to other teams). I've also included documentation and addressed the comments from Tobias's review.
