Make the code generator rip of dead constant expr uses before deciding whether a global is dead or not. This should fix PR3749 - linker adds spurious use to appending globals. I can't reasonably add a testcase for this, because the bc writer/reader strip dead constant users. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66404 91177308-0d34-0410-b5e6-96231b3b80d8
