static pgo: Does the compile flag ReadyToRunOptimizationData exists?

[martinbu]

The document describes an example how to compile static pgo with ReadyToRunOptimizationData.
I have traced the application with dotnet-trace, converted the nettrace file to the mbic format and add the mbic file as argument to the build with ReadyToRunOptimizationData. But I think the ReadyToRunOptimizationData does not exist...

Is this documentation correct or out-of-date?
