Same variable redefinition in gradient when different loops have the same counter variable name

[parth-07]

Gradient function contains variable redefinition error when different loops have the same counter variable name.

Reproducible example:

#include "clad/Differentiator/Differentiator.h"

double fn(double u, double v) {
    double res = 0;
    for (int i = 0; i < 5; ++i) {
      res += i;
    }
    for (int i = 0; i < 5; ++i) {
      res += i;
    }
    return res;
}

int main() {
    auto fn_grad = clad::gradient(fn);
}

_d_i is defined two times in the gradient function fn_grad.
