commit 1ab61656f71e94ce12b68de87f1e28cf3dc0c18c

Don't advertise RDRAND in cpuid for Core-i7-4910-like avx2 machine.
Bug#353370. In amd64g_dirtyhelper_CPUID_avx2 we set the RDRAND bit
but we don't implement support for RDRAND. Turn the bit off so programs
don't try to use RDRAND when running under valgrind.
