[PATCH] D16424: [ThinLTO] Do metadata linking during batch function importing

[Mehdi AMINI via llvm-commits]

What I have in mind is to `rememberAndSkipMetadata()` when parsing the module. But embedded the implementation in `BitcodeReaderMetadataList` so that whenever we call `getValueFwdRef` we don't create a placeholder (if the ID is one of the module-level constant) but parse the metadata on-demand. I should be able to craft something quickly.
