For the record, this test reveals another issue that original iv cand is not
considered:
Group 0:
Type: REFERENCE ADDRESS
Use 0.0:
At stmt:_1 = final_counts[i_21];
At pos: final_counts[i_21]

Also, when calling move_fixed_address_to_symbol, fixed_address_object_p looks
too restricted, it only considers link time constant address. In this case,
it's an array object in stack.

On AArch64, iovpts generates following code:
[local count: 954449108]:
# crc_20 = PHI
# ivtmp.5_18 = PHI <1(2), ivtmp.5_17(5)>
_19 = &final_counts + 18446744073709551612;
_1 = MEM[base: _19, index: iv

Haha..., get_address_cost() will cost down some address which is not my
expected, you
can get that code from my the 1st comment, i can not understand why adding that
code
