  // Transforms declarations so that in the end each declaration contains only one declarator.
  // This is useful as an intermediate step when initialization needs to be separated from
  // declaration, or when things need to be unfolded out of the initializer.
  // Examples:
  // Input:
  //     int a[1] = int[1](1), b[1] = int[1](2);
  // Output:
  //     int a[1] = int[1](1);
  //     int b[1] = int[1](2);
  // Input:
  //    struct S { vec3 d; } a, b;
  // Output:
  //    struct S { vec3 d; } a;
  //    S b;
  // Input:
  //    struct { vec3 d; } a;
  // Output (note: no change):
  //    struct { vec3 d; } a;
  // Input:
  //    struct { vec3 d; } a, b;
  // Output:
  //    struct s1234 { vec3 d; } a;
  //    s1234 b;
  // Input:
  //   struct Foo { int a; } foo();
  // Output:
  //   struct Foo { int a; };
  //   Foo foo();
  // Input with separateCompoundStructDeclarations=true:
  //    struct S { vec3 d; } a;
  // Output:
  //    struct S { vec3 d; };
  //    S a;
  // Input with separateCompoundStructDeclarations=true:
  //    struct S { vec3 d; } a, b;
  // Output:
  //    struct S { vec3 d; };
  //    S a;
  //    S b;
  // Input with separateCompoundStructDeclarations=true:
  //    struct { vec3 d; } a, b;
  // Output:

  //    s1234 a;
  //    s1234 b;
