Make debug info work when using -save-temps.
- This is pretty ugly, but the most obvious solution. Chime in if you
have a nicer one.
- The problem is that with -save-temps, clang-cc has no idea what the
name of the original input file is. However, the user expects to be
able to set breakpoints based on the input file name.
- We support this by providing a new option -main-file-name (similar
to -dumpbase used by gcc) which allows the driver to pass in the
original file name.
- <rdar://problem/6753383> building with clang using --save-temps
gets the compile unit name from the .i file...
