For PR723:
Support detection of a "CVS" directory at configure time to distinguish whether this is a release build or a "from tree" build. This knowledge is used to set the defaults for --enable-optimzied and --enable-assertions options. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27487 91177308-0d34-0410-b5e6-96231b3b80d8
