Check consistency of the PPC-specific flag 'UseSIGTRAP' with 'ImplicitRangeChecks' and 'ImplicitNullChecks'

Because 'UseSIGTRAP' is CPU-specific but ImplicitNullChecks is OS-dependent and ImplicitRangeChecks is CPU-specific a well, we do these consistency checks in 'src/cpu/ppc/vm/vm_version_ppc.cpp' and 'src/os/aix/vm/os_aix.cpp' respectively instead of clobbering the shared 'arguments.cpp'. It would be nice though to have a kind of platform dependent 'do_pd_flag_adjustments()' method but unfortunately this is not the case yet.
