testcase: Add testcase for tree-optimization/117341

Even though PR 117341 was a duplicate of PR 116768, another
testcase this time C++ does not hurt to have.
The testcase is a self-contained and does not use directly libstdc++
except for operator new (it does not even call delete).

Tested on x86_64-linux-gnu with it working.
