Currently we hand-code a set of phases when draining is allowed. However, this set of phases is conservative. The critical invariant is simply that the write barrier must be enabled if we're draining. Shortly we're going to enable mutator assists during the scan phase, which means we may drain during the scan phase. In preparation, this commit generalizes these assertions to check the fundamental condition that the write barrier is enabled, rather than checking that we're in any particular phase.

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.
