This is actually a difference between debug and release builds of
LLVM. Release builds are configured to drop all names for efficiency,
but debug builds keep them. So you need to rebuild LLVM with (I think)

Of course, the actual IR and names will still be different, and likely
in incompatible ways. The bitcode format is more stable, and LLVM-5.0
should be able to read .bc files generated by LLVM 3.8 (though not the
other way round).
