DeepEqual caches addresses of compared values
each time it visits addressable values. This is
more expensive than actually comparing them in
the common case of large slices of bytes or integers.
Also add a fast path for slices with identical

This CL makes resolveInternetAddr return a list of addresses that
contain a pair of different address family IP addresses if possible,
but doesn't contain any API behavioral changes yet. A simple IP
address selection mechanism for Resolve{TCP,UDP,IP}Addr and Dial API
still prefers IPv4.
This is in preparation for TCP connection setup with fast failover on
dual IP stack node as described in RFC 6555.

This change allows people who want to parse or set odd X.509 extensions
to do so without having to add support for them all to the package.
I tried to make it so that only a single member: Extensions would be
needed. However, that would mean detecting when the caller had altered
the contents of it so that parsing and marshaling a certificate
wouldn't ignore all changes to the other members. This ended up being
messy, thus the current design where there are two members: one for
reading and another for writing.
As crypto/x509 adds support for more extensions in the future, the raw
extensions will still be in Extensions for older code that expects it
there. Also, future extensions will be overridden by any raw extensions
added to ExtraExtensions by code that was written before support was
added.

When searching for an allocated bit, flushptrbuf would search
backward in the bitmap word containing the bit of pointer
being looked-up before searching the span. This extra check
was not replicated in markonly which, instead, after not
finding an allocated bit for a pointer would directly look in
the span.
Using statistics generated from godoc, before this change span
lookups were, on average, more common than word lookups. It
was common for markonly to consult spans for one third of its
pointer lookups. With this change in place, what were
previously span lookups are overwhelmingly become by the word
lookups making the total number of span lookups a relatively
small fraction of the whole.
This change also introduces some statistics gathering about
lookups guarded by the CollectStats enum.

The method is simple: the parser just parses
{{if A}}a{{else if B}}b{{end}}
