[PATCH] D24118: [JumpThreading] Only write back branch-weight MDs for blocks that originally had PGO info

Can you show me an example of

"The profile data seems odd. There is a single profile sample of the
loop being entered. On the other hand, there are no weights inside the
loop."

I want to know what is going on? Are your using FE PGO or IR PGO?
