Add cortex-a53.a57 target for 32 bit big/little.

Browse source 
The routines optimized for cortex-a7 and cortex-a53 cause performance
drops on cortex-a57. Instead create a target that is the middle ground
that works relatively well on either core.

# This file represents the best optimized routines that are the middle
# ground when running on a big/little system that is cortex-a57/cortex-a53.
# The cortex-a7 optimized routines, and the cortex-a53 optimized routines
# decrease performance on cortex-a57 processors by as much as 20%.
