target-tricore: Add instructions of RRR1 opcode format, which have 0x83 as first opcode
Add helpers:
* add64_ssov: adds two 64 bit values and saturates the result.
* addr_h/_ssov: adds two halfwords with two words in q-format with rounding
/ and saturates each result independetly.
Add microcode generator:
* gen_add64_d: adds two 64 bit values.
* gen_addsub64_h: adds/subtracts one halfwords with a word and adds/
subtracts another halftword with another word.
* gen_madd_h/s_h: multiply four halfwords, add each result left justfied
to two word values / and saturate each result.
* gen_maddm_h/s_h: multiply four halfwords, add each result left justfied
to two words values in q-format / and saturate each
result.
* gen_maddr32/64_h/s_h: multiply four halfwords, add each result left
justfied to two halftwords/words values in q-format
/ and saturate each result.
