RISC-V Patches for 3.1-rc2

This pull request contains four patches that aren't really related to
each other aside from all being bug fixes that I think should go in for
3.1.0:

* The second half of Alistair's memory leak patch set that I missed last
  week.
* A fix to make fclass.d availiable only on RV64IFD systems (without
  this it's availiable on RV32IFD systems, truncating the result).
* A fix to make sfence.vm availiable only in priv-1.9.1, and sfence.vma
  only availiable in priv-1.10.
* A change to respect fences in user-mode emulators, which were
  previously treated as NOPs.

As usual, this builds and boot Linux for me.  I don't think I have
anything else planned for 3.1.0, but I may be wrong as things are a bit
hectic this week.
