squid 3.2 doesn't cache requests for numerical hosts

[Alexander Komyagin]

Hi! I noticed that for numeric hosts requests, Squid 3.2 (transparent)
won't cache them. The problem is that HttpRequest::cacheable()returns
false due to the following check: 

    if (!flags.hostVerified && (flags.intercepted ||
flags.spoof_client_ip))
        return false;

Reason: ClientRequestContext::hostHeaderIpVerify(...) is called for
numeric hosts verification, but it does NOT set
http->request->flags.hostVerified in case of success.

Attached patch fixes the issue.
