Consider using -fno-omit-frame-pointer in release builds

    Description

      We're currently building with -fomit-frame-pointer, which can lead to cryptic stack traces.

      Switching to -fno-omit-frame-pointer will produce better stack traces but cost some performance. In my past experience, on x86-64 the penalty was around 0.5% (though on different code and with a different register allocator) which I think is a reasonably tradeoff but in corner cases it can be higher. So we'd need to qualify this change through a perf regression run (both benchmarks and primitives).
