Russ Cox a479a45548 reflect: make Value an opaque struct 
Making Value opaque means we can drop the interface kludges
in favor of a significantly simpler and faster representation.
v.Kind() will be a prime candidate for inlining too.

On a Thinkpad X201s using -benchtime 10:

benchmark                           old ns/op    new ns/op    delta
json.BenchmarkCodeEncoder           284391780    157415960  -44.65%
json.BenchmarkCodeMarshal           286979140    158992020  -44.60%
json.BenchmarkCodeDecoder           717175800    388288220  -45.86%
json.BenchmarkCodeUnmarshal         734470500    404548520  -44.92%
json.BenchmarkCodeUnmarshalReuse    707172280    385258720  -45.52%
json.BenchmarkSkipValue              24630036     18557062  -24.66%

benchmark                            old MB/s     new MB/s  speedup
json.BenchmarkCodeEncoder                6.82        12.33    1.81x
json.BenchmarkCodeMarshal                6.76        12.20    1.80x
json.BenchmarkCodeDecoder                2.71         5.00    1.85x
json.BenchmarkCodeUnmarshal              2.64         4.80    1.82x
json.BenchmarkCodeUnmarshalReuse         2.74         5.04    1.84x
json.BenchmarkSkipValue                 77.92       103.42    1.33x

I cannot explain why BenchmarkSkipValue gets faster.
Maybe it is one of those code alignment things.

README 

This is the source code repository for the Go programming language.  

For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install.html in your web browser.

After installing Go, you can view a nicely formatted
doc/install.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install.html.

Unless otherwise noted, the Go source files are distributed
under the BSD-style license found in the LICENSE file.

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README).  You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:

    export GOROOT=$HOME/go
    export PATH=$PATH:$GOROOT/bin

See doc/install.html for more details.
