asm-mem: add testcase for missing reload after asm memops
Memory simplification is done with the help of the function
dominates() which determine when memory instructions interfere.
This function handles OP_CALLs, OP_LOADs and OP_STOREs but
memory can also be changed via OP_ASMs.
Add a testcase showing this.
