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)

bool ok = false;
void f(){ ok = true; } void main() { bool b=true; b && f(); assert(ok); }
