* mips.igen (mips32r2, mips64r2): New ISA models. Add new model tags to all instructions which are applicable to the new ISAs. (do_ror, do_dror, ROR, RORV, DROR, DROR32, DRORV): Add, moved from vr.igen. * mips3264r2.igen: New file for MIPS 32/64 revision 2 specific instructions. * vr.igen (do_ror, do_dror, ROR, RORV, DROR, DROR32, DRORV): Move to mips.igen. * configure.ac (mipsisa32r2*-*-*, mipsisa64r2*-*-*): Add new targets. * configure: Regenerate.
