* sub_h_ssov/suov: Sub two halfword and saturate on overflow.
* absdif_h_ssov: Compute absolute difference for halfwords and saturate on overflow.
* abs_h_ssov/suov: Compute absolute value for two halfwords and saturate on overflow.
* abs_b/h: Compute absolute value for four/two bytes/halfwords
* absdif_b/h: Compute absolute difference for four/two bytes/halfwords
* add_b/h: Add four/two bytes/halfwords.
* sub_b/h: Sub four/two bytes/halfwords.
* eq_b/h: Compare four/two bytes/halfwords with four/two bytes/halfwords on
equality and set all bits of to either one ore zero.
* eqany_b/h: Compare four/two bytes/halfwords with four/two bytes/halfwords on equality.
* lt_b/bu/h/hu: Compare four/two bytes/halfwords with four/two bytes/halfwords
on less than signed and unsigned.
* max_b/bu/h/hu: Calculate max for four/two bytes/halfwords signed and unsigned.
* min_b/bu/h/hu: Calculate min for four/two bytes/halfwords signed and unsigned.
Add helper function abs_ssov, that computes the absolute value for a 32 bit integer and saturates on overflow.
Add microcode generator functions:
* gen_sub_CC: Caluclates sub and sets the carry bit.
* gen_subc_CC: Caluclates sub and carry and sets the carry bit
* gen_abs: Compute absolute value for a 32 bit integer.
* gen_cond_w: Compares two 32 bit values on cond and sets result either zero or all bits one.
OPC2_32_RR_MIN switched with OPC2_32_RR_MIN_U.

The mask is actually 7 bit long, instead of 6, so the expression checking
for JNZ.T is always false. Let's make the mask 1 bit wider.

Since all the TriCore instructionsets are subsets of each other (1.3 C 1.3.1 C 1.6),
make the features implying each other, e.g 1.6 also has 1.3.1 and 1.3. This way
we only need to check our features for the instructionset, where a instruction was first introduced.
