Philipp Oppermann 5735cb8ec0 Do a volatile read in stack_overflow test to avoid tail recursion ...

This prevents the compiler from transforming the tail recursive function into a loop, which does not lead to a stack overflow. It also avoids the LLVM bug where functions with side-effect-free endless loops are removed. Thus, the test now also works in `--release` mode.
