Fix a latent bug in the asm code. I think that technically, using "*m0" instead of "*0" allows LLVM to pick between using the same memory as output 0 and using a new memory location. (So far I haven't been able to construct a testcase that actually breaks because of this, though)

struct bar {
    int bar;
}

void main() {
    bar Bar;
    with (Bar)
    {
        assert(Bar.bar == 0);
        void test()
        {
            bar ++;
        }
        test();
    }
    assert(Bar.bar == 1);
}
