This version follows the suggestion I made earlier of treating 32-bit floating point registers as a "plain" register for O32 rather than a floating-point register.  It seems to work for me though for O32 I've only tested with 32-bit floating point registers.  If we stick with this approach for 32-bit floating point it might be simpler and/or more readable to make _floats[] an array of uint32_t for that case and just use different context sizes for the O32 with 32-bit fp vs O32 with 64-bit fp.  This version works in my testing on FreeBSD for O32 with 32-bit FPR, N32, and N64.
