target-tricore: Add instructions of RRR1 opcode format, which have 0xc3 as first opcode

Add helpers helper_addsur_h/_ssov which adds one halfword and subtracts one
halfword, rounds / and saturates each half word independently.

Add microcode helper functions:
    * gen_maddsu_h/sus_h: multiply two halfwords left justified and add to the
                          first one word and subtract from the second one word
                          / and saturate each resulting word independetly.
    * gen_maddsum_h/sums_h: multiply two halfwords in q-format left justified
                            and add to the first one word and subtract from
                            the second one word / and saturate each resulting
                            word independetly.
    * gen_maddsur32_h/32s_h: multiply two halfwords in q-format left justified
                             and add to the first one word and subtract from
                             the second one word, round both results / and
                             saturate each resulting word independetly.
