This adds the `mov_f_ru6` and `mov_cc_f_ru6` instruction formats. Adding the `f` flag to these instructions revealed a bug in the u6 decoding (details to be explained in context below). This u6 decoding bug is fixed here.

Many new decoder test cases have also been added, exercising the changes mentioned above in addition to further exercising predicated binary instructions (the support for these was added here https://reviews.llvm.org/rG1cda1e618648d463f89eb5cea8c9849bc0074b24, but that patch only tested predicated rsub).
