[PATCH] D59837: Add "git llvm revert" subcommand

The current git-svnrevert script only works with git-svn repos (e.g. using "git svn find-rev" to find the commit to revert). This adds a similar implementation that works with the llvm git command handler.

Usage:

  // Revert by svn id
  $ git llvm revert r123456
  // Forgetting the 'r' is fine
  $ git llvm revert 123456
  // Git commit hash also fine
  $ git llvm revert abc123456
  // Push revert upstream (drop the -n)
  $ git llvm push -n

Regardless of how the command is invoked (with a svn revision or git hash), the message is:

  Revert [LibFoo] Change Foo implementation
  
  This reverts r123456 (git commit abc123)
