This patch adds tunes for 32-bit armv8 platforms. The user can select
the vector floating-point instruction set: vfpv3, vfpv4 or fp-armv8
and the Neon, crc and crypto extensions.
Also, fix some parsing failures for armv7a*-neon-vfpv4 tunes.

Any plans for 64 bit version?
Andrei
Yes, we have plans to add specific tunes for armv8 64bit too, but after
we finish for 32bit.
For the moment, for 64bit, we simply include arch-armv8.inc witch only
require arch-arm64.inc.
Regards,
Daniel
