target-tricore: Add instructions of RR1 opcode format, that have 0xb3 as first opcode
Add instructions of RR1 opcode format, that have 0xb3 as first opcode.
Add helper functions mulh, mulmh and mulrh, that compute multiplication,
with multiprecision (mulmh) or rounding (mulrh) of 4 halfwords, being either low or high parts
of two 32 bit regs.
