Done, thanks for the reminder!

Not done; I had considered this, but the bit lives in a CPUID leaf that is not currently supported at all by the header or Host.cpp.  I'm willing to add RDPRU, with FIXMEs for the other feature bits, if people want it.

Done.  For some reason I thought the clang intrinsic test would verify this, but actually it doesn't.
