[WebAssembly] Handle weak undefined functions with a synthetic stub This error case is described in Linking.md. The operand for call requires generation of a synthetic stub. Differential Revision: https://reviews.llvm.org/D44028 llvm-svn: 327151

[WebAssembly] Add --[no]-export-dynamic to replace --export-default In a very recent change I introduced a --no-export-default flag but after conferring with others it seems that this feature already exists in gnu GNU ld and lld in the form the --export-dynamic flag which is off by default. This change replaces export-default with export-dynamic and also changes the default to match the traditional linker behaviour. Now, by default, only the entry point is exported. If other symbols are required by the embedder then --export-dynamic or --export can be used to export all visibility hidden symbols or individual symbols respectively. This change touches a lot of tests that were relying on symbols being exported by default. I imagine it will also effect many users but do think the change is worth it match of the traditional behaviour and flag names. Differential Revision: https://reviews.llvm.org/D52587 llvm-svn: 343265
