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

Yes, we have plans to add specific tunes for armv8 64bit too, but
after we finish for 32bit.<br>
For the moment, for 64bit, we simply include arch-armv8.inc witch
only require arch-arm64.inc.<br>
