When building shared libraries, all symbols on Allsym are marked reachable. What I didn't realize was that this includes the ".dup" symbols created when "dupok" symbols are read from multiple package files. This breaks now because deadcode makes some assumptions that fail for these ".dup" symbols, but in any case was a bad idea -- I suspect this change makes libstd.so a bunch smaller, but creating it was broken before this CL so I can't be sure. This change simply stops adding these symbols to Allsym, which might make some of the many iterations over Allsym the linker does a touch quicker, although that's not the motivation here. Add a test that no symbols called ".dup" makes it into the runtime shared library.

The Go Programming Language
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
For documentation about how to install and use Go, visit https://golang.org/ or load doc/install-source.html in your web browser.
Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.
Go is the work of hundreds of contributors. We appreciate your help!
To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html
Note that we do not accept pull requests and that we use the issue tracker for bug reports and proposals only. Please ask questions on https://forum.golangbridge.org or https://groups.google.com/forum/#!forum/golang-nuts.

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 file). 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-source.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 https://golang.org/doc/install or doc/install.html for more details.
