565591d8 - [LoopUnroll] Do not copy !llvm.loop from latch to non-latch (#165635)

[LoopUnroll] Do not copy !llvm.loop from latch to non-latch (#165635) When LoopUnroll copies the original loop's latch to the corresponding non-latch branch in an unrolled iteration, any `!llvm.loop` is copied along with it, but `!llvm.loop` is useless and misleading there. This patch discards it. e06831a3b29d did the same for LoopPeel.
