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 mini.norun_debug7;

int gi;

void main()
{
    int* fail;
    *fail = 0;
}
