Can you move this to SharedSymbol? This increases the size of SymbolBody at least one byte, but this field is not going to be used except for SharedSymbol.

No `else` after `continue`.

----------------
Add a brief comment here to say that we don't know the exact alignment requirement for the data copied by a copy relocation, so align that to 16 byte boundaries (which we think is large enough) unconditionally.
