* interp.c (sim_open): Add support for bfd_arch_v850_rh850

	architecture type.  Add support for bfd_mach_v850e2 and
	bfd_mach_v850e2v3 machine numbers.
        * v850.igen (dbtrap): Add support for SIM_OPEN_DEBUG.
        (cmpf.d): Correct order of operands.
        (cmpf.s): Likewise.
        (trncf.dul): New pattern.
        (trncf.duw): New pattern.
        (trncf.sul): New pattern.
        (trncf.suw): New pattern.
        * v850-dc: Correct bitfield selection for TRNCF.SW and CVTF.SW.
