Currently, tfork on openbsd/mips64 returns the thread ID on success and
a negative error number on error. In CL#447175, newosproc was changed
to assume that a non-zero value is an error - return zero on success to
match this expectation.

This test exercises the case where a net.Conn error occurs while
writing a response body. It injects an error by setting a timeout
on the Conn. If this timeout expires before response headers are
written, the test fails. The test attempts to recover from this
failure by extending the timeout and retrying.
Set the timeout after the response headers are removed, and
remove the retry loop.

Besides this CL removes the unnecessary alignment of the DWORD

lfstack does very unsafe things. In particular, it will not
work with nodes that live on the heap. In normal use by the runtime,
that is the case (it is only used for gc work bufs). But the lfstack
test does use heap objects. It goes through some hoops to prevent
premature deallocation, but those hoops are not enough to convince
-d=checkptr that everything is ok.
Instead, allocate the test objects outside the heap, like the runtime
does for all of its lfstack usage. Remove the lifetime workaround
from the test.

For a while now, we've had intermittent reports about problems with
os/exec on macOS, but no clear way to reproduce them. Recent changes
in the os/exec package test seem to have aligned the stars just right,
at least on my two x86 and ARM MacBook Pro laptops, to make the
package test hang with roughly 50% probability. When it does hang, the
stacks I see in the hung process match the ones reported for the
Go-based hangs in #33565. (They do not match the ones reported in the
so-called C reproducer in that issue, but I think that reproducer is
actually reproducing a different race, between fork and exit.)
The stacks obtained from the hung child processes are in
libSystem_atfork_child, which is supposed to reinitialize various
parts of the C library in the new process.
One common stack dies in _notify_fork_child calling _notify_globals
(inlined) calling _os_alloc_once, because _os_alloc_once detects that
the once lock is held by the parent process and then calls
_os_once_gate_corruption_abort. The allocation is setting up the
globals for the notification subsystem. See the source code at [1].
To work around this, we can allocate the globals earlier in the Go
program's lifetime, before any execs are involved, by calling any
notify routine that is exported, calls _notify_globals, and doesn't do
anything too expensive otherwise. notify_is_valid_token(0) fits the bill.
The other common stack dies in xpc_atfork_child calling
_objc_msgSend_uncached which ends up in
WAITING_FOR_ANOTHER_THREAD_TO_FINISH_CALLING_+initialize. Of course,
whatever thread the child is waiting for is in the parent process and
is not going to finish anything in the child process. There is no
public source code for these routines, so it is unclear exactly what
the problem is. However, xpc_atfork_child turns out to be exported
(for use by libSystem_atfork_child, which is in a different library,
so xpc_atfork_child is unlikely to be unexported any time soon).
It also stands to reason that since xpc_atfork_child is called at the
start of any forked child process, it can't be too harmful to call at
the start of an ordinary Go process. And whatever caches it needs for
a non-deadlocking fast path during exec empirically do get initialized
by calling it at startup.
This CL introduces a function osinit_hack, called at osinit time,
which calls notify_is_valid_token(0) and xpc_atfork_child().
Doing so makes the os/exec test pass reliably on both my laptops -
I can run it successfully hundreds of times in a row when my previous
record was twice in a row.

Currently for every CPU profile sample, we apply its weight to all
call edges of the entire call stack. Frames higher up the stack
are unlikely to be repeated calls (e.g. runtime.main calling
main.main). So adding weights to call edges higher up the stack
may be not reflecting the actual call edge weights in the program.
This CL changes it to add weights to only the edge between the
last two frames.
Without a branch profile (e.g. LBR records) this is not perfect,
but seems more reasonable.

when we compute the CDF we already have a list of hot call sites
that make up the given percentage of the CDF, just use that list.
Also, when computing the CDF threshold, include the very last node
that makes it to go over the threshold. (I.e. if the CDF threshold
is 50% and one hot node takes 60% of weight, we should include that
node instead of excluding it. In practice it rarely matters,
probably only for testing and micro-benchmarks.)

Recognizing the `clear` built-in early is not causing any problems:
if existing code defines a `clear`, that will be used as before. If
code doesn't define `clear` the error message will make it clear
that with 1.21 the function will be available. It's still possible
to define a local `clear` and get rid of the error; but more likely
the name choice should be avoided going forward, so this provides a
useful early "heads-up".

When it reports a parse error, it uses the "value" variable as the
value element of the parse error. Previously, in some of the cases,
the "value" variable is always updated to the next chunk of the value
to be parsed (even if an earlier chunk is invalid). The reported
parse error is confusing in this case.
This CL addresses this issue by holding the original value, and when
it fails to parse the time, use it to create the parse error.
Fixes#56730.

Given code like
func itou(i int) uint { return uint(i) }
var x = itou(-1)
the static inliner from CL 450136 was rewriting the code to
var x = uint(-1)
which is not valid Go code. Fix this by converting the
constants appropriately during inlining.
Fixes golang.org/x/image/vector test.

In -race mode, the dist test command only registers the std, race,
osusergo, and amd64ios tests before returning early from
(*tester).registerTests. Prior to CL 450018, the osusergo and amd64ios
tests weren't even affected by -race mode, so it seems their inclusion
was unintentional. CL 450018 lifted the logic to run tests in race
mode, which means these tests went from running without -race to
running with -race. Unfortunately, amd64ios is not compatible with
-race, so it is now failing on the darwin-amd64-race builder.
Fix this by omitting the osusergo and amd64ios tests from -race mode,
since it seems like they were really intended to be included anyway.
This should fix the darwin-amd64-race builder.
Updates #37486.

testenv.HasCgo reports whether the test binary may have been built
with cgo enabled, but having been built with cgo does not necessarily
imply that the test can invoke the cgo tool itself.
This should fix a test failure on the android builders introduced in
CL 450714.

Don't test IsLocal("nul.txt"), since whether this name is reserved
