[PATCH] D15922: [NOP][Cloning] Add comment to cloneLoopWithPreheader() mentioningthat it does not update LoopInfo for sub-loops.

[Adam Nemet via llvm-commits]

anemet added a comment.

Good point, thanks.

Can you please also add an assert to check that there are no subloops in OrigLoop?

We could also rename the function to cloneInnerLoopWithPreheader?
