Set of patches containing implementations for some instructions that
were missing before. Also, moves some related instructions to
decodetree. Add mffsce test.

v2:
- Added R-b on patches 1, 8, 10, and 11. Dropped the R-b on some
  of the patches as there were big changes on them.
- Fixed addg6s issues
- Separated do_mffsc in two different, more specialized functions
- Changed mffs* patches order to make it more readable, as suggested
  by Richard
- Added a new patch with a test for the mffsce instruction
