This revision now requires changes to proceed.

If LTO does change the IR in some way that would drop local_unnamed_addr, it will not be present in the .o that is passed to the linker.

So the linker can decide if it is valid to hide the symbol by looking at all the input files, bitcode or not, including the ones produced by LTO.
