Nelson Chu 595e49a4b7 RISC-V: Support SiFive extensions: xsfvqmaccdod, xsfvqmaccqoq and xsfvfnrclipxfqf ...

Those SiFive extensions have been published on the web for a while, and we plan
to implement intrinsics in GCC for those instructions soon.

NOTE: The original patch was written by Nelson when he was still working at
SiFive, and Kito rebased it to the trunk. Therefore, I kept the author as Nelson
with his SiFive email.
