[OPENMP] Fix PR36399: Crash on C code with ordered doacross construct. Codegen for ordered with doacross construct might produce incorrect code because of missing cleanup scope for the construct. Without this scope the final runtime function call could be emitted in the wrong order that leads to incorrect codegen. llvm-svn: 325304
