The function is here ONLY for symmetry with package bytes.
This function should be used ONLY if it makes code clearer.
It is not here for performance. Remove any performance benefit.

If performance becomes an issue, the compiler should be fixed to
recognize the three-way compare (for all comparable types)
rather than encourage people to micro-optimize by using this function.

Since the move to Github, we've started to receive lots of
introductory questions to the bug tracker. I posit this is because
most projects on Github don't have mailing lists, so the culture on
Github is to use the Issue Tracker as a discussion forum.

The Go project doesn't use the Issue Tracker as our first point of
communication. This CL updates CONTRIBUTING.md (which is linked when
you file a bug or send a pull request), to mention that we have a
mailing list.

It certainly won't stop all the errant bug reports, but it should
help.

This brings in cmd/dist written in Go, which is working on the primary builders.

If this breaks your build, you need to get Go 1.4 and put it in $HOME/go1.4
(or, if you want to use some other directory, set $GOROOT_BOOTSTRAP
to that directory).

To build Go 1.4 from source:

	git clone -b release-branch.go1.4 $GOROOT $HOME/go1.4
	cd $HOME/go1.4/src
	./make.bash

Or use a binary release: https://golang.org/dl/.

See https://golang.org/s/go15bootstrap for more information.

Moving the "don't really preempt" check up earlier in the function
introduced a race where gp.stackguard0 might change between
the early check and the later one. Since the later one is missing the
"don't really preempt" logic, it could decide to preempt incorrectly.
Pull the result of the check into a local variable and use an atomic
to access stackguard0, to eliminate the race.

I believe this will fix the broken OS X and Solaris builders.
