[PATCH] D29438: [XRay] Probe for CPU features that XRay needs

[Martin Pelikán via Phabricator via llvm-commits]

Nitpick (user-first): When false, the user will only see "Some CPU features are missing", not which ones.  I'd do another Report in the amd64 function specifically bragging about RDTSCP.  Most of these will be because of people running in too-restrictive VMs and will be resolved by "d'oh!" and fixing the support.
