Sixth chunk split out of https://reviews.llvm.org/D41954.

Must be committed simultaneously with LLD change, DXXX.

Changes:
--------

- Change the WASM_SYMBOL_INFO linking metadata to refer to symbols by index rather than by string name
- This should reduce the size of the Wasm object files. Hopefully uncontroversial?
