It uses -O1 -fdump-tree-store_ccp and tests for lack of link_error,
but note that store_ccp is enabled with -O2 or higher.
So the testcase is testing something that happens in
some other optimizer like DOM.

A quick grep for fdump-tree-store_ccp shows
20030731-2.c:/* { dg-options "-O1 -fdump-tree-store_ccp" } */
20030917-1.c:/* { dg-options "-O1 -fdump-tree-store_ccp" } */
20030917-3.c:/* { dg-options "-O1 -fno-tree-dominator-opts
-fdump-tree-store_ccp" } */
20040721-1.c:/* { dg-options "-O2 -fdump-tree-store_ccp-vops" } */
ssa-ccp-1.c:/* { dg-options "-O1 -fdump-tree-store_ccp" } */
ssa-ccp-2.c:/* { dg-options "-O1 -fdump-tree-store_ccp" } */
ssa-ccp-3.c:/* { dg-options "-O1 -fdump-tree-store_ccp" } */
ssa-ccp-7.c:/* { dg-options "-O1 -fdump-tree-store_ccp" } */
ssa-ccp-9.c:/* { dg-options "-O1 -fdump-tree-store_ccp" } */
So store_ccp isn't enabled in most of these.
