RFR: 8313080: [lw5] javac parser is not accepting some array types with nullness markers

[Vicente Romero]

Code like:


class Test {
    void m(Test[][] t1, Test[][][] t2) {
        Test[][]! l1 = (Test[][]!) t1;
        Test[][][]! l2 = (Test[][][]!) t2;

        Test[]![]! l3 = (Test[]![]!) t1;
        Test[]![]![]! l4 = (Test[]![]![]!) t2;
    }
}


is being rejected by javac. Basically the compiler can't deal with nullness markers interleaved in array type declarations. This patch is fixing this issue.
