Functions
Profile	llvm::xray::mergeProfilesByThread (const Profile &L, const Profile &R)
	This algorithm will merge two Profile instances into a single Profile instance, aggregating blocks by Thread ID.
Profile	llvm::xray::mergeProfilesByStack (const Profile &L, const Profile &R)
	This algorithm will merge two Profile instances into a single Profile instance, aggregating blocks by function call stack.
Expected< Profile >	llvm::xray::loadProfile (StringRef Filename)
	This function will attempt to load an XRay Profiling Mode profile from the provided |Filename|.
Expected< Profile >	llvm::xray::profileFromTrace (const Trace &T)
	This function takes a Trace and creates a Profile instance from it.
