New Revision: 137753

URL: http://llvm.org/viewvc/llvm-project?rev=137753&view=rev
Log:
DIBuilder is moving forward to reduce in memory use by MDNodes. However, DIFactory does not emit debug info in updated form.
Use LLVMDebugVersion10 directly here so that debug info nodes produced by DIFactory do not claim to adhere newer structure.
