e0584e96c1 sha/asm/keccak1600-armv4.pl: optimize for Thumb-2. 
Reduce per-round instruction count in Thumb-2 case by 16%. This is
achieved by folding ldr/str pairs to their double-word counterparts.

d9ca12cbf6 sha/asm/keccak1600-armv4.pl: improve non-NEON performance by ~10%. 
This is achieved mostly by ~10% reduction of amount of instructions
per round thanks to a) switch to KECCAK_2X variant; b) merge of
almost 1/2 rotations with logical instructions. Performance is
improved on all observed processors except on Cortex-A15. This is
because it's capable of exploiting more parallelism and can execute
original code for same amount of time.
