Fangrui Song	ab550c798f	[CMake] Change -DENABLE_EXPERIMENTAL_NEW_PASS_MANAGER=off to -DLLVM_ENABLE_NEW_PASS_MANAGER=off ... LLVM_ENABLE_NEW_PASS_MANAGER is set to ENABLE_EXPERIMENTAL_NEW_PASS_MANAGER, so -DLLVM_ENABLE_NEW_PASS_MANAGER=off has no effect. Change the cache variable to LLVM_ENABLE_NEW_PASS_MANAGER instead. A user opting out the new PM needs to switch from -DENABLE_EXPERIMENTAL_NEW_PASS_MANAGER=off to -DLLVM_ENABLE_NEW_PASS_MANAGER=off. Also give a warning that -DLLVM_ENABLE_NEW_PASS_MANAGER=off is deprecated.
