MIPS: Add some instructions to uasm.

Follow on patches for eBPF JIT require these additional instructions:

   insn_bgtz, insn_blez, insn_break, insn_ddivu, insn_dmultu,
   insn_dsbh, insn_dshd, insn_dsllv, insn_dsra32, insn_dsrav,
   insn_dsrlv, insn_lbu, insn_movn, insn_movz, insn_multu, insn_nor,
   insn_sb, insn_sh, insn_slti, insn_dinsu, insn_lwu

... so, add them.

Sort the insn_* enumeration values alphabetically.
