The new device runtime uses an internal variable to set debugging. This variable was originally privately linked because every module will have a copy of it. This caused problems with merging the device bitcode library because it would get renamed and there was not a way to refer to an external, private symbol. This changes the symbol to weak_odr so it can be defined multiply, but will not be renamed. Reviewed By: jdoerfert Differential Revision: https://reviews.llvm.org/D109997
