Subject: [PATCH] Simplify and clean up "update" target. Also add an
 SVN-UPDATE-OPTIONS variable that controls the update behaviour. This allows
 to go to a common older revision of all svn directories:

  gmake update SVN-UPDATE-OPTIONS=-r47717

would rewind both llvm and clang to a common
revision (if clang is checked out into the llvm
tree).


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47717 91177308-0d34-0410-b5e6-96231b3b80d8
