GVN Load PRE can split the backedge causing breaking the loop structure where the latch contains the conditional branch with for example induction variable. Different optimizations expect this form of the loop, so it is better to preserve it for some time. This CL adds an option to control an ability to split backedge. Default value is true so technically it is NFC and current behavior is not changed.
