add floating point register saving/restoring to mips setjmp/longjmp
also fix the alignment of jmp_buf to meet the abi. linux always emulates fpu on mips if it's not present, so enabling this code unconditionally is "safe" but may be slow. in the long term it may be preferable to find a way to disable it on soft float builds.
