This lets the queries work on Windows as well as Linux. This does mean make and cmake aren't using the same scripts to do the queries (again), but at least GetSVN.cmake understands git and git-svn as well as svn now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223425 91177308-0d34-0410-b5e6-96231b3b80d8

# CMake project that writes Subversion revision information to a header.

# FIRST_SOURCE_DIR - First source directory

# FIRST_NAME - The macro prefix for the first repository's info
