<summary>Changes</summary>
1. For {get_icall_data_read_write, get_icall_data_read_write_with_weight, get_icall_data_read_write_big_endian}, extract common code into `testICallDataReadWrite`
- Add helper function `addValueProfData` and `testValueDataArray`. This two helper functions are used by `testICallDataReadWrite`, and possibly other test cases.
3. Split test case `get_icall_data_merge1_saturation` into two smaller test cases, `test_block_counter_merge_saturation` for block counter merge saturation, and `test_icall_data_merge_saturation` for value profile merge saturation.
- With the test case split, add helper function `testValueProfileMergeSaturation` so it could be re-used by a new kind of value profiles.
4. For test case `get_icall_data_merge_site_trunc`, extract common code into a helper function `testValueProfileMergeTrunc` so it could be re-used by a new kind of value profiles.
