Ingvar Stepanyan d3252bb1bb Add LTO for C++ builds (#755)
* Add LTO for C++ builds

This didn't have much effect on fastcomp builds, but provides further size savings with new LLVM backend we switched to in #750 (and fixes the MozJPEG size regression from the same PR).

In the future we won't need to pass `--llvm-lto 1` explicitly, but latest Emscripten Docker image doesn't contain the Emscripten version with the necessary fixes for this.

* Delete build.log
