[PATCH] D71249: [LV] Set and preserve name of vector preheader block.

Herald added a project: LLVM.

Current implementation sets "vector.ph" name to preheader block only if block split happened. With this change we unconditionally set the name of vector preheader block to "vector.ph". That helps understanding code structure better.
