Goroutine 1:
Call Read on read half of pipe, entering pipeHalf.rw.
Check ioclosed field, which is false.
Send data to p.c1
Wait for response on p.c2.
Goroutine 2:
Call Close on read half of pipe, entering pipeHalf.close.
Set closed field.
Send error to p.cclose.
Set ioclosed field.
Send 1 to p.done.
Return and exit goroutine.
Goroutine 3:
This is the goroutine running pipe.run, and for some reason
it has started late.
Read error from p.rclose; set rerr and continue.
Read 1 from p.done; increment ndone and continue.
Read data from r1 (sent by goroutine 1); set r1 = nil and continue
Now goroutine 1 is waiting for a response, and goroutine 3 is
waiting for something else to happen.
This patch fixes the race by having the runner check whether
the read half is closed when it is asked for read data, and
similarly for the corresponding race on the write half.
This patch also fixes the similar race in which ndone gets
bumped up to 2 while there is a reader or writer waiting.
There is still another race to fix. It is possible for the
read half and the write half to both be closed, and for the
runner goroutine to exit, all before the runner goroutine sees
the request from a reader. E.g., in the above, have goroutine
2 also close the write half, and have goroutine 3 see both
done messages before it sees the request from goroutine 1.

(Here, quoted strings are the official AMD names.)
The amd64 "movsxd" instruction, when invoked
with a 64-bit REX prefix, moves and sign extends
a 32-bit value from register or memory into a
64-bit register. 6.out.h spells this MOVLQSX.
6.out.h also includes MOVLQZX, the zero extending
version, which it implements as "movsxd" without
the REX prefix. Without the REX prefix it's only sign
extending 32 bits to 32 bits (i.e., not doing anything
to the bits) and then storing in a 32-bit register.
Any write to a 32-bit register zeros the top half of the
corresponding 64-bit register, giving the advertised effect.
This particular implementation of the functionality is
non-standard, because an ordinary 32-bit "mov" would
do the same thing.
Because it is non-standard, it is often mishandled or
not handled by binary translation tools like valgrind.
Switching to the standard "mov" makes the binaries
work better with those tools.
It's probably useful in 6c and 6g to have an explicit
instruction, though, so that the intent of the size
change is clear. Thus we leave the concept of MOVLQZX
and just implement it by the standard "mov" instead of
the non-standard 32-bit "movsxd".

One goroutine started up and was waiting in rw. Then another
goroutine decided to close the pipe. The closing goroutine
stalled calling p.io.Lock() in pipeHalf.close. (This happened
in gccgo). If the closing goroutine had been able to set the
ioclosed flag, it would have gone on to tell the runner that
the pipe was closed, which would then send an EINVAL to the
goroutine sleeping in rw. Unlocking p.io before sleeping in
rw avoids the race.

This shortens, simplifies and regularizes the code significantly.
(Improvements to reflect could make another step.)
Passes all.bash.
One semantic change occurs: The String() method changes
behavior. It used to run only for string formats such as %s and %q.
Instead, it now runs whenever the item has the method and the
result is then processed by the format as a string. Besides the
regularization, this has three effects:
1) width is honored for String() items
2) %x works for String() items
3) implementations of String that merely recur will recur forever
Regarding point 3, example from the updated documentation:
type X int
func (x X) String() string { return Sprintf("%d", x) }
should cast the value before recurring:
func (x X) String() string { return Sprintf("%d", int(x)) }
