RFR: 8290432: C2 compilation fails with assert(node->_last_del == _last) failed: must have deleted the edge just produced

[Yi Yang]

Hi, can I have a review for this patch? [JDK-8273585](https://bugs.openjdk.org/browse/JDK-8273585) recognized the form of `Phi->CastII->AddI` as additional parallel induction variables. In the following program:

class Test {
    static int dontInline() {
        return 0;
    }

    static long test(int val, boolean b) {
        long ret = 0;
        long dArr[] = new long[100];
        for (int i = 15; 293 > i; ++i) {
            ret = val;
            int j = 1;
            while (++j < 6) {
                int k = (val--);
                for (long l = i; 1 > l; ) {
                    if (k != 0) {
                        ret += dontInline();
                    }
                }
                if (b) {
                    break;
                }
            }
        }
        return ret;
    }

    public static void main(String[] args) {
        for (int i = 0; i < 1000; i++) {
            test(0, false);
        }
    }
}

`val` is incorrectly matched with the new parallel IV form:

And C2 further replaces it with newly added nodes, which finally leads the crash:

I think we can add more constraints to the new form. The form of `Phi->CastXX->AddX` appears when using Preconditions.checkIndex, and it would be recognized as additional IV when 1) Phi != phi2, 2) CastXX is controlled by RangeCheck(to reflect changes in Preconditions checkindex intrinsic)
