        child node, so subsequent statements are just tucked to the parent
        Compound. Additionally, consecutive (fall-through) case statements
        come out messy. This is a peculiarity of the C grammar. The following:

switch (myvar) {
                case 10:
                    k = 10;
                    p = k + 1;
                    return 10;
                case 20:
                case 30:
                    return 20;
                default:
                    break;
            }

Creates this tree (pseudo-dump):

Switch
                ID: myvar
                Compound:
                    Case 10:
                        k = 10
                    p = k + 1
                    return 10
                    Case 20:
                        Case 30:
                            return 20
                    Default:
                        break

The goal of this transform is to fix this mess, turning it into the
        following:

Switch
                ID: myvar
                Compound:
                    Case 10:
                        k = 10
                        p = k + 1
                        return 10
                    Case 20:
                    Case 30:
                        return 20
                    Default:
                        break

A fixed AST node is returned. The argument may be modified.

        conferring a qualifier upon the contained type.

This function fixes a decl with atomic specifiers to have a sane AST
        structure, by removing spurious Typename->TypeDecl pairs and attaching
        the _Atomic qualifier in the right place.
