Add helpers helper_addsur_h/_ssov which adds one halfword and subtracts one
halfword, rounds / and saturates each half word independently.
Add microcode helper functions:
* gen_maddsu_h/sus_h: multiply two halfwords left justified and add to the
first one word and subtract from the second one word
/ and saturate each resulting word independetly.
* gen_maddsum_h/sums_h: multiply two halfwords in q-format left justified
and add to the first one word and subtract from
the second one word / and saturate each resulting
word independetly.
* gen_maddsur32_h/32s_h: multiply two halfwords in q-format left justified
and add to the first one word and subtract from
the second one word, round both results / and
saturate each resulting word independetly.
