    target-mips: add mips16 instruction decoding · 364d4831

    There's no good way to add this incrementally, so we do it all at once.
    The only changes to shared code are in handle_delay_slot.  We need to
    flip ISAMode when doing a jump-and-exchange.  We also need to set
    ISAMode the low bit of the target address for jump-to-register.
    Also, since we're now adding bits that can be in MIPS_HFLAG_BMASK_EXT,
    make sure we use MIPS_HFLAG_BMASK_BASE in the places where we just want
    basic information about a branch.
