(gcn_goacc_validate_dims): Turn on worker partitioning unconditionally.
(gcn_fork_join): Update comment.
* config/gcn/gcn.opt (flag_worker_partitioning): Remove.
(macc_experimental_workers): Remove unused option.

[acc_device_radeon]: Update.
* testsuite/libgomp.oacc-c-c++-common/loop-dim-default.c
[ACC_DEVICE_TYPE_radeon]: Likewise.
