Difference when compiling human readable IR vs bitcode with clang frontend
We've noticed a difference in the embedded bitcode when compiling human readable IR to an object directly vs first compiling IR to BC and then an object through clang -cc1.
If the original IR file contained an "llvm.compiler.used" gv, it will be preserved when compiling IR -> BC -> Obj.
When compiling IR -> Obj directly, it will be removed.
