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)

module bug39;

struct S
{
    long l;
}

void main()
{
    S s;
    s.l = 23;
    void* p = &s;
}
