Do not synchronize Add(1) with Wait().
Imitate read on first Add(1) and write on Wait(),
it allows to catch common misuses of WaitGroup:
- Add() called in the additional goroutine itself
- incorrect reuse of WaitGroup with multiple waiters

Revision 01810e5c68e9 added the following to src/pkg/runtime/stack.h:

        StackPreempt = (uintptr)(intptr)0xffffade,

The typedef for intptr is defined in two places:

        1. src/pkg/runtime/runtime.h for use by the runtime

        2. include/u.h for use by the compilers and linkers

On Plan 9, we don't use include/u.h but instead augment the host's
u.h with extra typedefs. These are in include/plan9/GOARCH/u.h.

We forgot to add intptr. It didn't cause a problem until now since
that typedef was never used outside the runtime.

Normally the codereview plugin disables adding new commits
when not using the submit command. Unfortunately this makes
it impossible to use the Mercurial Queues extension at the
same time.

A feature called "Phases" was introduced in Mercurial 2.1
that allows marking commits as being secret; this means
they will never be pushed to the upstream repository.

We can take advantage of this feature to allow the use of
Mercurial Queues if the mq.secret option has been set in
hgrc(5) and a recent version of Mercurial is used.
