Marko Mäkelä 99a481b28e Use Intel intrinsic functions for RDSEED and RDRAND ...

Starting with GCC 9 or clang 9, we can actually use <immintrin.h>
without any problems. We only have to flag such
functions where such instructions are being used.

The benefit of using intrinsic functions over inline assembler
is that the compiler is given more flexibility. In particular,
clang -fsanitize=memory (MemorySanitizer, MSAN) will not raise
bogus alarms about memory being uninitialized.

Both intrinsic functions are available starting with GCC 5 and
clang 3.8. The RDRAND wrapper is available starting with clang 3.7
via <immintrin.h>. Before GCC 9 and clang 9, the RDSEED wrapper is
not available via <immintrin.h> but via <x86intrin.h>, and only after
jumping through some hoops to enable it.
