Test program to reproduce GCC 12 compilation bug

Here is the expected output of the ppc9_test_sat_add_090923.cpp test program:
Test completed successfully

The ppc9_test_sat_add_090923.cpp test program results in the following output
when compiled with GCC 12 with -O2 -mcpu=power9 -std=c++14:
Expected vector not equal to actual
Aborted (core dumped)

The ppc9_test_sat_add_090923.cpp test program does generate the expected
results when compiled with GCC 11 with the -O2 -mcpu=power9 -std=c++14 options.
