I want a single place where the evaluate::TargetCharacteristics is being set-up, and it will need an llvm::DataLayout, which can only be obtained from an llvm::TargetMachine.

The other solution is to move the SemanticContext outside of CompilerInvocation, but I am not sure of the implications. Would that be possible?
