David Crawshaw f81ae3b22c cmd/link: shorter type symbol names 
Use (part of) a SHA-1 checksum to replace type symbol names.

In typical programs this has no effect because types are not included
in the symbol table. But when dynamically linking, types are in the
table to make sure there is only one *rtype per Go type.

Eventually we may be able to get rid of all pointers to rtype values in
the binary, but probably not by 1.7. And this has a nice effect on
binary size today:

libstd.so:
	before 27.4MB
	after  26.2MB

For #6853.

The Go Programming Language

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

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.
