Manuel Barrio Linares ec6ba8e7ca refactor md5.body function to reduce instruction count
- replaced manual unrolling with loop structures and constant arrays
- instruction count reduced from 12445 to 4016
- maybe about 1 to 2% performance loss on some benchs but take this
number with a grain of salt.
