Make == for associative arrays test for equality, not identity. _aaEq was added to runtime/internal/aaA.d which forwards to TypeInfo_AssociativeArray.equals in genobj.d. On the codegen side, DtoAAEquals was added to gen/aa.cpp and is called from EqualExp::toElem in gen/toir.cpp. I assume that the frontend will produce an error if == is used on associative arrays of different type. This fixes DMD bug 1429.

extern(C) int printf(char*, ...);

long foo(ref int p) {
    try { return 0; }
    finally {
        p++;
        throw new Object;
    }
}

void main() {
    int p = 0;
    try {
        foo(p);
        assert(0);
    } catch {
    }
    printf("Number of types scope(exit) was executed : %d\n", p);
    assert(p == 1);
}
