[PATCH] D47806: [WebAssembly] Add --export-all flag

[Sam Clegg via Phabricator via llvm-commits]

This causes all symbols to be exported in the final wasm binary
even if they were not compiled with default visibility.

This feature is useful for the emscripten toolchain that has a
corresponding EXPORT_ALL feature which allows the JS code to
interact with all C function.
