arch-armv7a.inc, feature-arm-vfp.inc: add tunes for vfpv3 and vfpv3d16
This adds tunes for ARM's v3 Vector Floating Point unit for
16 and 32 bit implementation:
http://www.arm.com/products/processors/technologies/vector-floating-point.php
See also https://wiki.debian.org/ArmHardFloatPort/VfpComparison
for a nice comparison and why vfpv3d16 is useful.
