Summary: Allow predefined styles to define different options for different languages so that one can run: clang-format -style=google file1.cpp file2.js or use a single .clang-format file with "BasedOnStyle: Google" for both c++ and JS files. Added Google style for JavaScript with "BreakBeforeTernaryOperators" set to false.
