Reapply "Change -save-temps to emit unoptimized bitcode files." This reapplies r224503 along with a fix for compiling Fortran by having the clang driver invoke gcc (see r224546, where it was reverted). I have added a testcase for that as well. Original commit message: It is often convenient to use -save-temps to collect the intermediate results of a compilation, e.g., when triaging a bug report. Besides the temporary files for preprocessed source and assembly code, this adds the unoptimized bitcode files as well. This adds a new BackendJobAction, which is mostly mechanical, to run after the CompileJobAction. When not using -save-temps, the BackendJobAction is combined into one job with the CompileJobAction, similar to the way the integrated assembler is handled. I've implemented this entirely as a driver change, so under the hood, it is just using -disable-llvm-optzns to get the unoptimized bitcode. Based in part on a patch by Steven Wu. rdar://problem/18909437 llvm-svn: 224688 2014-12-21 15:00:00 +08:00			`// Check that the clang driver can invoke gcc to compile Fortran.`
