target-tricore: Fix mask handling JNZ.T being 7 bit long
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.

target-tricore: Change SSOV/SUOV makro name to SSOV32/SUOV32
Those makros are exclusively used for 32 bit arithmetics and won't work for
16 bit with two halfwords. So lets get rid of the len parameter and make them
always use 32 bit. Now no token pasting is needed anymore and they can be
regular functions.

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.
