Skeleton documentation for the RISC-V port
During the upstreaming process it was suggested that I add a handful of small documentation entries about the RISC-V port, which I've collected here. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * manual/math.texi: RISC-V supports _Float128 and _Float64x.
