amdgcn: Fix exec register live-on-entry to BB in md-reorg

This patch fixes a corner case in the AMD GCN md-reorg pass when the
EXEC register is live on entry to a BB, and could be clobbered by code
inserted by the pass before a use in (e.g.) a different BB.

* config/gcn/gcn.c (gcn_md_reorg): Fix case where EXEC reg is live
on entry to a BB.
