This patch adds the actual implementation for GCN. A variant would be
to only generate .offload_func_table inside mkoffload when
OMP_REQUIRES_REVERSE_OFFLOAD has been requested.
This is currently effectively a no op as with [1/3] patch, always NULL
is passed and as GOMP_OFFLOAD_get_num_devices returns <= 0 as soon as
'omp requires reverse_offload' has been specified.
OK for mainline?
