Backwards compatibility with the LLVM IR textual format is not guaranteed,
while bitcode compatibility is. You can probably load up that old IR by
assembling it with an old llvm-as and loading the bitcode in new clang.
That said, if it's just a matter of skipping over the 'metadata' token, it
would be nice to let old IR assemble.
