[PATCH] D62443: [WebAssembly] Move Emscripten-specific behavior under a --emscripten flag

[Sam Clegg via Phabricator via llvm-commits]

sbc100 added a comment.

Can you rebase now that https://reviews.llvm.org/D62744 has landed?

Maybe worth splitting out the isImplicitlyUsed part of this change too?  especially since the llvm side of that is still being discussed.
