This series contains implentation of CA32 and OV32 bits added to the 
ISA 3.0. Various fixed-point arithmetic instructions are updated to take
care of the newer flags. 

Finally the last patch adds new instruction mcrxrx, that helps reading 
the carry (CA and CA32) and the overflow (OV and OV32) flags

Changelog:
v1: 
* Use these ISA 3.0 flag to enable CA32 and OV32
* Re-write ca32 compute routine
* Add setting of flags for "neg." and "nego."
