Subject: [binutils-gdb] sim: cris/frv/h8300/iq2000/lm32/m32r/sh64: standardize cpu state

commit f95f4ed2c4680fea68399691481b277ece11570e
Author: Mike Frysinger <vapier@gentoo.org>

    sim: cris/frv/h8300/iq2000/lm32/m32r/sh64: standardize cpu state
    
    This sets up the sim_state structure and the cpu member to match what we
    do in most other sims, and what the common code suggests.  This is a step
    to unifying on the sim-cpu.o object.
