#     powerpc/xmon: Fix opcode being uninitialized in print_insn_powerpc
#     
#     When building with -Wsometimes-uninitialized, Clang warns:
#     
#       arch/powerpc/xmon/ppc-dis.c:157:7: warning: variable 'opcode' is used
#       uninitialized whenever 'if' condition is false
#       [-Wsometimes-uninitialized]
#         if (cpu_has_feature(CPU_FTRS_POWER9))
#             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#       arch/powerpc/xmon/ppc-dis.c:167:7: note: uninitialized use occurs here
#         if (opcode == NULL)
#             ^~~~~~
#       arch/powerpc/xmon/ppc-dis.c:157:3: note: remove the 'if' if its
#       condition is always true
#         if (cpu_has_feature(CPU_FTRS_POWER9))
#         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#       arch/powerpc/xmon/ppc-dis.c:132:38: note: initialize the variable
#       'opcode' to silence this warning
#         const struct powerpc_opcode *opcode;
#                                            ^
#                                             = NULL
#       1 warning generated.
#     
#     This warning seems to make no sense on the surface because opcode is set
#     to NULL right below this statement. However, there is a comma instead of
#     semicolon to end the dialect assignment, meaning that the opcode
#     assignment only happens in the if statement. Properly terminate that
#     line so that Clang no longer warns.
