Manu Linares 4b03a84b00 optimize test_ct_intlog2 test and whirlpool hash (#2938)
* optimize `test_ct_intlog2` while still covering all 128 bit positions

* refactor whirlpool to reduce code bloat

replaced the fully unrolled round loop with a runtime loop, reducing
instruction count by 80k in `process_block` and yielding aprox 30%
performance boost due to improved cache locality.

* use compile-time arrays for `test_ct_intlog2`
