for compare-fp-1:
iuneq same
ieq improved (using movf)
iltgt have to look more into (since I am comparing 4.3 vs 4.6)
ine same
iunlt improved (using movf)
ilt improved (using movf)
ile improved (using movf)
iungt improved (using movf)
igt improved (using movf)
iunge improved (using movf)
ige have to look more into (since I am comparing 4.3 vs 4.6)
I noticed that these all could be improved even more by using movf more and
better jump threading.
