[amdgcn] Silence warnings + add gcc_unreachable()
* config/gcn/gcn.c (gcn_expand_scalar_to_vector_address, gcn_md_reorg): Remove unused variables. (gcn_emutls_var_init): Add missing (but unreachable) return to silence warning. (gcn_hsa_declare_function_name): Add gcc_unreachable to ensure target != TARGET_GCN3 or TARGET_GCN3 will fail instead of use an uninitialized variable. From-SVN: r278678
