Initial Emscripten support
- Target: wasm32-emscripten (wasm32-unknown-emscripten).
- Compiler id: clang-emscripten (type clang, variant emscripten, class gcc).
- Ability to build executables (.js plus .wasm) and static libraries (.a). Set
executable bit on the .js file (so it can be executed with a suitable binfmt
interpreter).
- Default config.bin.lib for wasm32-emscripten is static instead of both.
- Full C++ exception support is enable unless disabled explicitly by the user
with -s DISABLE_EXCEPTION_CATCHING=1|2.
- The bin module registers the wasm{} target type for wasm32-emscripten.
