Restrict implicit cast from pointers to generic type variables to void*. The purpose of generic type variables is to not lose information about types. Implicit casts to void* defeats the purpose.

Wer're planning to restrict casts to and from void pointers in checked scopes (issue #571). This seems like something that should be considered as part of implementing that. For unchecked scopes, there doesn't seem to be a good reason to treat casts between void * and pointer to generic type variables diffrently than other pointer cats. Closing this as redundant with issue #571.

Add -output-dir and other file handling improvements (#412)
5300cf8 
- Add -output-dir option to write updated files to a directory structure
  parallel to the base dir (#347). When -output-dir is used, a source
  file outside the base dir can't be handled because there is no way to
  compute its output path. For consistency, this is now an error even
  when -output-dir is not used.

- Convert all 3C regression tests from -output-postfix to -output-dir to
  avoid leaving temporary files in the clang/test/3C directory (#378).

- Expand "3c -help" documentation. In particular, direct the user to pass
  "--" when they don't want to use a compilation database to avoid
  accidentally using unwanted compiler options and suppress the warning
  if no compilation database is found (#343).

- For consistency, have stdout mode output the main file even if it is
  unchanged (#328).

- Fix bugs in matching of file paths against the base dir (#327).

- Other minor bug fixes: see the pull request description for details.
