Devang Patel 5049600672 GlobalOpt only process non constant local GVs while optimizing global vars.
If non constant local GV named A is used by a constant local GV named B (e.g. llvm.dbg.variable) and B is not used by anyone else then eliminate A as well as B.

In other words, debug info should not interfere in removal of unused GV.
