Make sure that for any DLL that Go uses itself, we only look for the
DLL in the Windows System32 directory, guarding against DLL preloading
attacks.
(Unless the Windows version is ancient and LoadLibraryEx is
unavailable, in which case the user probably has bigger security
problems anyway.)
This does not change the behavior of syscall.LoadLibrary or NewLazyDLL
if the DLL name is something unused by Go itself.
This change also intentionally does not add any new API surface. Instead,
x/sys is updated with a LoadLibraryEx function and LazyDLL.Flags in:

TestCrashDumpsAllThreads carefully sets the number of Ps to one
greater than the number of non-preemptible loops it starts so that the
main goroutine can continue to run (necessary because of #10958).
However, if GC starts, it can take over that one spare P and lock up
the system while waiting for the non-preemptible loops, causing the
test to eventually time out. This deadlock is easily reproducible if
you run the runtime test with GOGC=1.
Fix this by forcing GOGC=off when running this test.

This bug was introduced in golang.org/cl/18217,
while trying to fix #13777.
Originally I wanted to just disable inlining for the case
being handled incorrectly, but it's fairly difficult to detect
and much easier just to fix. Since the case being handled
incorrectly was inlined correctly in Go 1.5, not inlining it
would also be somewhat of a regression.
So just fix it.
Test case copied from Ian's CL 19520.
The mistake to worry about in this CL would be relaxing
the condition too much (we now print the note more often
than we did yesterday). To confirm that we'd catch this mistake,
I checked that changing (!fmtbody || !t.Funarg) to (true) does
cause fixedbugs/issue13777.go to fail. And putting it back
to what is written in this CL makes that test pass again
as well as the new fixedbugs/issue14331.go.
So I believe that the new condition is correct for both constraints.
Fixes #14331.

TestInterfaceAddrsWithNetsh invokes Windows netsh command passing
it a particular interface name. This approach somehow does not work
on some computers (see issue for details). Change that to call netsh
without specifying any interface name. This provides output for all
interfaces available. So we can achieve same goal parsing this output.
Also makes test faster because we only need to invoke netsh once.

We used to include panic calls in tracebacks; however, when
runtime.panic was renamed to runtime.gopanic in the conversion of the
runtime to Go, we missed the special case in showframe that includes
panic calls even though they're in package runtime.
Fix the function name check in showframe (and, while we're here, fix
the other check for "runtime.panic" in runtime/pprof). Since the
"runtime.gopanic" name doesn't match what users call panic and hence
isn't very user-friendly, make traceback rewrite it to just "panic".

churn is high, allocation rate is high, or when there are many

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.
Fixes #14232
