// 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, b;
// Output:
//    struct s1234 { vec3 d; } a;
//    s1234 b;
