Updating revisions.pl.in:
- Change the way the LLVM SVN revision is detected, using `svn info` instead
of `svnversion`. This speeds it up significantly on my machine (especially
when the LLVM SVN checkout isn't in disk cache).
- Add "last changed date" to SVN checkouts too, not just unpacked tarballs
- No longer rely on SVN revision to detect release vs trunk checkouts, treat
release checkout the same as unpacked release tarball. (Except for date
determination, which uses SVN date instead of filesystem date)
