- Added support for invoking the Swift frontend via "swift_driver -frontend". - Added frontend_main.cpp, which implements the main entry point for the integrated frontend. (Currently, this supports compiling an input Swift file into an object file.) - Removed lib/Frontend/FrontendOptions.td, and replaced its functionality with options in include/Swift/Driver/Options.td and a new include/Swift/Driver/FrontendOptions.td. Options supported by the frontend are denoted by the FrontendOption flag; options which are not supported by the driver are denoted by the NoDriverOption flag. - Updated CompilerInvocation::parseArgs() to use the option table returned from createDriverOptTable(), including renaming a handful of options. (-triple is now -target, and -Xclang is now -Xcc.) Swift SVN r11082
