[PATCH v3 0/3] libgomp: OpenMP low-latency omp_alloc

[Andrew Stubbs]

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.
