This patch series is an implementation of the vector divide, vector
divide extended and vector modulo instructions from PowerISA 3.1
The first patch are Matheus' patch, used here since the divs256 and
divu256 functions use int128_urshift.
Patches without review: 2, 4, 5 and 8
v3 changes:
- Divided DO_VDIV_VMOD macro in 4 different new macros
- Turned TRANS_VDIV_VMOD into a function and the instructions are
now implemented with the TRANS macro and do_vdiv_vmod function
- Moved clz128 to int128.h
v2 changes:
- Dropped int128_lshift patch
- Added missing int_min/-1 check
- Changed invalid division to a division by 1
- Created new macro responsible for invalid division check
(replacing DIV_VEC, REM_VEC and the check in dives_i32/diveu_i32)
- Turned GVecGen3 array into single element
