GlobalVariable I inserted gets removed by LTO
Hello llvm-dev@ I have a pass that puts a global constant data array into the module. And another pass that gets runned by lld during LTO stage. When I look at bytecode files corresponding to source TUs produced by `clang -flto`, I can see GVs inserted by my pass #1. However, when pass #2 gets to run, these GV's are gone. I figured out that passing -mllvm -compute-dead=0 to the linker fixes
