For the added needwritebarrier call, the right arg doesn't

the write barrier.  The left arg is the one that matters.

Given GOPATH=p1:p2 and source code of just the right form,
the go command could previously end up invoking the compiler
with -I p2 -I p1 or the linker with -L p2 -L p1, so that
compiled packages in p2 incorrectly shadowed packages in p1.
If foo were in both p1 and p2 and the compilation of bar
were such that the -I and -L options were inverted in this way,
then

	GOPATH=p2 go install foo
	GOPATH=p1:p2 go install bar

would get the p2 copy of foo instead of the (expected) p1 copy of foo.

This manifested in real usage in a few different ways, but in all
the root cause was that the -I or -L option sequence did not
match GOPATH.

Make it match GOPATH.

The operation where this manifested in a crash was % (only defined on integers).
However, the existing code was sloppy in that it didn't retain the integer form
after a value (e.g., 3.0) was accepted as representable in integer form (3 for
the example). We would have seen a crash in such cases for / as well except
that there was code to fix it for just that case.

Remove the special code for / and fix more generally by retaining the integer
form for all operations if applicable.

The test sends two HTTP/1.1 pipelined requests.  The first is
completedly by the second, and as such triggers an immediate call to the
CloseNotify channel.  The second calls the CloseNotify channel after the
overall connection is closed.

The test was passing fine on gc because the code would enter the select
loop before running the handler, so the send on gotReq would always be
seen first.  On gccgo the code would sometimes enter the select loop
after the handler had already finished, meaning that the select could
choose between gotReq and sawClose.  If it picked sawClose, it would
never close the overall connection, and the httptest server would hang.
The same hang could be induced with gc by adding a time.Sleep
immediately before the select loop.

Deflake the test by 1) don't close the overall connection until both
requests have been seen; 2) don't exit the loop until both closes have
been seen.

When using a stack-allocated buffer for the result, don't
expose the uninitialized portion of it by restricting its
capacity to its length.

The other option is to zero the portion between len and cap.
That seems like more work, but might be worth it if the caller
then appends some stuff to the result.  But this close to 1.6,
I'm inclined to do the simplest fix possible.
