target-tricore: Add instructions of RRR1 opcode format, which have 0xa3 as first opcode
Add helpers:
* sub64_ssov: subs two 64 bit values and saturates the result.
* subr_h/_ssov: subs two halfwords from two words in q-format with rounding
/ and saturates each result independetly.
Add microcode generator:
* gen_sub64_d: adds two 64 bit values.
* gen_msub_h/s_h: multiply four halfwords, sub each result left justfied
from two word values / and saturate each result.
* gen_msubm_h/s_h: multiply four halfwords, sub each result left justfied
from two words values in q-format / and saturate each
result.
* gen_msubr32/64_h/s_h: multiply four halfwords, sub each result left
