[PATCH 4/5] vcruntime140_1: Unwind state 0.

[Daniel Lehman]

Signed-off-by: Daniel Lehman

'last' points to state 0 so the (unwind_data > last) stops too soon
and a handler for state 0 is skipped

void throw_int(int x)
{
    test t(0xcafef00d); /* at 0 */
    throw x;
}

void test_unwind_to_minus_one(void)
{
    try {
        throw_int(42);
    } catch(int i) {
        printf("catch %d\n", i);
    }
}
