target-tricore: Add instructions of RRR1 opcode format, which have 0x63 as first opcode

Add helpers:
    * msub64_q_ssov: multiply two 32 bit q-format number, sub the result from a
                     64 bit q-format number and saturate.
    * msub32_q_sub_ssov: sub two 64 bit q-format numbers and return a 32 bit
                         result.
    * msubr_q_ssov: multiply two 32 bit q-format numbers, sub the result from a 32 bit
                    q-format number and saturate.
    * msubr_q: multiply two 32 bit q-format numbers and sub the result from a 32 bit
               q-format number.
