This change fixes a serious performance regression with reflect.Value growing to 4 words instead of 3. The json benchmark was ~50% slower, with this change it is ~5% slower (and the binary is 0.5% larger). Longer term, we probably need to rethink our copy generation. Using REP is really expensive time-wise. But inlining the copy grows the binary. R=golang-codereviews, r CC=golang-codereviews https://golang.org/cl/44990043 |

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.
