It introduced stack-use-after-return detected by ASAN.

Here:
'''

  auto &&CodeGen = [ELoc](CodeGenFunction &CGF) {
    CGF.CGM.getOpenMPRuntime().emitForStaticFinish(CGF, ELoc);
  };
  CodeGen(CGF);
  CGF.OMPCancelStack.back().CodeGen = CodeGen;

'''

CodeGen is function on the stack and CGF.OMPCancelStack.back().CodeGen is a
reference which will be used after return from the function with CodeGen.

This reverts commit r286944.
