There currently exists two identical testcase source files -- none/tests/ppc32/test_isa_2_06_part1.c and none/tests/ppc64/test_isa_2_06_part1.c. For ease of maintenance, the intention is to use the same source file for both the 32-bit and 64-bit tests, but I should have used a symbolic link instead of a copy. This is analogous to none/tests/ppc{32|64}/jm-insns.c, where the 64-bit file is a symbolic link to the 32-bit file. So we should remove none/tests/ppc64/test_isa_2_06_part1.c and replace it with a symbolic link to none/tests/ppc32/test_isa_2_06_part1.c.
