It's possible for the rs6000 prologue code to emit references to the
second-level toc using .LCTOC0@toc(2) but never have the label .LCTOC0 defined.
This testcase, compiled with -S -mminimal-toc -O0 demonstrates the problem.
long foo (long x)
{
return 0;
return x + 0x87654321;
}
Mainline happens to avoid the problem by trimming at the tree level with
expand_unreachable_stmt. All 3.3.x and 3.2.x compilers I tested have this problem.

Since this will always be fixed on the tree-ssa (by having DCE at the tree level) and it is not a
regression, I am suspending this.
