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.
