target-tricore: Add instructions of RRR opcode format
Add microcode generator function gen_cond_sub.
Add helper functions:
* ixmax/ixmin: search for the max/min value and its related index in a
vector of 16-bit values.
* pack: dack two data registers into an IEEE-754 single precision floating
point format number.
* dvadj: divide-adjust the result after dvstep instructions.
* dvstep: divide a reg by a divisor, producing 8-bits of quotient at a time.
OPCM_32_RRR_FLOAT -> OPCM_32_RRR_DIVIDE
