This patch adds the targets 'emscripten-wasm' and 'emscripten-js' to the build system so that either architectures can be specified when compiling the emscripten engine
…hitectures This patch modifies prebuilts so that each emscripten arch target has its own lib folder and set of prebuilt packages.
This patch adds source code stubs to resolve reported missing symbols while compiling & linking the emscripten standalone engine.
…sm build This patch modifies the build configuration files & tools in order to support upgrading the emscripten sdk to a version which produces wasm output using LLVM.
This patch updates the emscripten engine source to use the Asyncify API instead of the current Emterpreter API to suspend engine execution.
This patch removes the recursion block in the emscripten implementation of 'MCScreenDC::wait()', allowing wait to be called from script within the event loop.
This patch fixes a compiler error due to an unnecessary cast from int to off_t
…compile This patch updates the C define options added by using the prebuilt libskia library to match the values defined when the library is compiled
… version This patch updates the IDE standalone building & deploy scripts for emscripten to work with the new wasm version which involves changes to the name of files bundled with the standalone. in addition, the wasm file portion needs a 'Content-Type' header when accessed via HTTP for testing.
This patch updates the development documentation for building the emscripten engine. The instructions for building emscripten-js have been modified to describe how to install the deprecated tools needed, and a new section for building emscripten-wasm has been added.
This patch updates 'Installer/package.txt' to account for the switch to wasm object files in the emscripten standalone engine.

This patch significantly reduces the size of the javascript portion of the emscripten-wasm standalone engine by removing unnecessary JavaScript bindings to exported functions in the engine.
This patch modifies the build configuration of emscripten engines to optimize them for performance over filesize
This patch modifies 'buildbot.py' so that a BUILD_PLATFORM of 'emscripten' will produce compiled binaries for the 'emscripten-js' target

This patch adds a new emscripen-wasm build target and renames the current emscripten target to emscripten-js. This allows the building of both WebAssembly and asm.js versions of the emscripten standalone engine. In addition the standalone builder and deploy scripts have been modified to handle building HTML5 standalones using either of these target architectures.
