Rick Hudson 13aff7831d runtime: avoid redundant scans 
During a concurrent GC stacks are scanned in
an initial scan phase informing the GC of all
pointers on the stack. The GC only needs to rescan
the stack if it potentially changes which can only
happen if the goroutine runs.
This CL tracks whether the Goroutine has run
since it was last scanned and thus may have changed
its stack. If necessary the stack is rescanned.

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.
