add __divmoddi4 builtin

GCC 11 will generate it in code

void foo(unsigned char *u8Second, unsigned int *u32Nanosecond, long long timeSpec)
{
    long long i64Div;
    int i32Div;
    int i32Rem;
    i64Div = timeSpec;
    i32Rem = (int)(i64Div % 1000000000);
    i64Div /= 1000000000;
    *u32Nanosecond = i32Rem;
    i32Rem = (int)(i64Div % 60);
    *u8Second = i32Rem;
}
