Read and save configuration registers, up to 4. Config3 holds the micromips implementation info. Added isa implementation info to mips32_common. Added isa filter to avoid common mistakes, but only if one isa mode is implemented. When resuming the isa requested is set if more than one isa mode is implemented.
