Add tests of DIV by zero.
Added tests of DIV by zero. The tests exercise DIV by zero of all
supported data types in CTS/VTS and only expect runtime/drivers to not
crash.
Updated the reference implementation of INT32 DIV. Before this CL, the
reference implementation will crash with floating point exception. This
CL forces INT DIV by zero to return 0.
Fixes: 151151830
Test: NNT_static
