- Refactors the Emscripten target spec to share code with other wasm targets. - Replaces the incorrect wasm32 C call ABI with the old asmjs version, which is correct for both wasm32 and JS. - Updates the varargs ABI used by Emscripten and deletes the old one. - Removes the obsolete wasm32-experimental-emscripten target. - Temporarily makes Emscripten targets use panic=abort by default because supporting unwinding will require an LLVM patch.
