        R_PCRWORD_B.
        (rtype2howto): Handle R_PCRWORD_B.
        (h8300_reloc16_extra_cases): Handle R_PCRWORD_B.
        (h8300_reloc_16_estimate): Likewise.  Try to turn a 16bit
        pc-relative branch (R_PCRWORD) into an 8bit pc-relative
        branch (R_PCWORD_B).
So we can turn 16bit pcrel branches into 8bit pcrel branches on the H8/300H.
