We were checking the wrong bit for rdrand support. Found using SDE's
-ivb_rdrnd_cpuid option to toggle the bit off and on. Fortunately on
Intel processors the bit we were actually checking is also enabled by
Ivy Bridge. However it is also used on AMD Bulldozer processors to
signal half-precision floating point support so we could false
positive there.
