With pic, the load of the global's address is pulled outside the loop, so the
"base" is a register rather than the global.  This causes ivopts to represent
index*step all in the index field rather than as two separate fields, so the
dump looks like
  MEM[base: &arr_base, index: (int *) iter * 4B] = D.1877;
instead of
  MEM[symbol: arr_base, index: (int *) iter, step: 4B] = D.1877;
so the test fails, but the generated code is correct and optimal.  I suggest
adding -fno-pic to the test, does that look OK?
