This patch fixes a bug in which GCN5 devices often fail to return an
exit value because it's not yet been written to memory when the program
exits. The fix is simply to wait for it properly. GCN3 devices did not
demonstrate the problem, but it was technically wrong there also. The
bug was introduced when we stopped waiting for all writes to complete.
I've also taken the opportunity to adjust gcn-run such that a similar
issue can't go unnoticed for so long, in future.
Now backported to gcc-9-branch.
