If I'm not mistaken, the patch landed after 3.1 was cut. You can simply
patch this in yourself:
--- llvm/trunk/CMakeLists.txt 2012/05/07 19:38:40 156319
+++ llvm/trunk/CMakeLists.txt 2012/05/09 15:10:54 156472

set(PACKAGE_VERSION "${LLVM_VERSION_MAJOR}.${LLVM_VERSION_MINOR}svn")

-set_property(GLOBAL PROPERTY USE_FOLDERS ON)
+option(LLVM_USE_FOLDERS "Enable solution folders in Visual Studio. Disable
for Express versions." ON)
+if ( LLVM_USE_FOLDERS )
+ set_property(GLOBAL PROPERTY USE_FOLDERS ON)
+endif()

include(VersionFromVCS)

Cheers,
