Merge push_parser and pop_parser into a single parse_import function
and inline unimportfile. Shake out function boundaries a little bit so
that the symmetry is readily visible.
Move the import_package call into parse_import (and inline
import_there into import_package). This means importfile no longer
needs to provide fake import data to be needlessly lexed/parsed every
time it's called.
Also, instead of indicating import success/failure by whether the next
token is "package", import_spec can just check whether importpkg is
non-nil.
Tangentially, this somehow alters the diagnostics produced for
test/fixedbugs/issue11610.go. However, the new diagnostics are more
consistent with those produced when the empty import statement is
absent, which seems more desirable than maintaining the previous

would also be somewhat of a regression.

cmd/go: use GOPATH order for compile -I and link -L options
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.
Fixes #14176 (second report).
Fixes #14192.
Related but less common issue #14271 not fixed.

This error only affects the compilation of the standard library,

and an error about notexist being a non-standard package
(because the non-existant package is in fact not a standard package).

go/types: make sure constants valid in integer operations are in integer form
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.
Fixes #14229.

net/http: deflake TestCloseNotifierPipelined
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.
Fixes #14231.

runtime: don't expose stack buffer in stringto{byte,rune}slice
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.
