target-tricore: Add instructions of RRR1 opcode format, which have 0xe3 as first opcode
Add helpers helper_subadr_h/_ssov which subs one halfword and adds one
halfword, rounds / and saturates each half word independently.
Add microcode helper functions:
* gen_msubad_h/ads_h: multiply two halfwords left justified and sub from the
first one word and add the second one word
/ and saturate each resulting word independetly.
* gen_msubadm_h/adms_h: multiply two halfwords in q-format left justified
and sub from the first one word and add to
the second one word / and saturate each resulting
word independetly.
* gen_msubadr32_h/32s_h: multiply two halfwords in q-format left justified
and sub from the first one word and add to
the second one word, round both results / and
saturate each resulting word independetly.
