runtime: fix scheduler race condition
In starttheworld() we assume that P's with local work
are situated in the beginning of idle P list.
However, once we start the first M, it can execute all local G's
and steal G's from other P's.
That breaks the assumption above. Thus starttheworld() will fail
to start some P's with local work.
It seems that it can not lead to very bad things, but still
it's wrong and breaks other assumtions
(e.g. we can have a spinning M with local work).
The fix is to collect all P's with local work first,
and only then start them.

build: add intptr typedef for Plan 9
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.

codereview: don't warn about secret commits
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.
