These are routines written specifically for vendor CPUs, such as the
thunderx version of memcpy and memmove.  The HWCAP_CPUID allows for such
routines to be launched on the correct hardware, but when run under
valgrind, those routines will not get called and any potential bugs in
those routines may get masked.
