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 memory1;

extern(C) int printf(char*,...);

void main()
{
    auto a = new int[16];
    {printf("array.length = %u\n", a.length);}
    {a.length = a.length + 1;}
    {printf("array.length = %u\n", a.length);}
    {assert(a.length == 17);}
}
