Use a worklist to avoid a sneaky iterator invalidation. The iterator could be invalidated when it's recursively deleting a whole bunch of constant expressions in a constant initializer. Note: This was only reproducible if `opt' was run on a `.bc' file. If `opt' was run on a `.ll' file, it wouldn't crash. This is why the test first pushes the `.ll' file through `llvm-as' before feeding it to `opt'. PR15440 llvm-svn: 178531
