Some rules for PPC64 were checking for a case
where a shift followed by an 'and' of a mask could
be lowered, depending on the format of the mask. The
function to verify if the mask was valid for this purpose
was not checking if the mask was 0 which we don't want to
allow. This case can happen if previous optimizations
resulted in that mask value.
This fixes isPPC64ValidShiftMask to check for a mask of 0 and return
false.
This also adds a codegen testcase to verify it doesn't try to
match the rules in the future.

When linking internally on OpenBSD, dedup libraries treating versioned
and unversioned libraries as equivalents. Versioned libraries are preferred
and are retained over unversioned libraries.
This avoids the situation where the use of cgo results in a DT_NEEDED for a
versioned library (for example, libc.so.96.1), while a dynamic import
specifies an unversioned library (for example, libc.so). Without deduplication
this would result in two DT_NEEDED entries, causing a failure when ld.so
attempts to load the Go binrary.

CL 258938 changed the way C to Go calls work such that they now
construct a C struct on the C side for the arguments and space for the
results. Any pointers in the result space must be zeroed, so we just
zero the whole struct.
However, C makes it surprisingly hard to robustly zero any struct
type. We had used a "{0}" initializer, which works in the vast
majority of cases, but fails if the type is empty or effectively
empty.
This CL fixes this by changing how the cgo tool zero-initializes the
argument struct to be more robust.

In chansend() and chanrecv() of chan.go, the order of calls to
raceacquire() and racerelease() was swapped, which meant that the
code was not following the memory model "by the letter of the law."
Similar for bufrecv and bufsend in select.go
The memory model says:
- A send happens before the corresponding receive completes, and
- the kth receive on a channel with capacity C happens before the
k+C send on that channel completes.
The operative word here is "completes." For example, a sender obtains
happens-before information on completion of the send-operation, which
means, after the sender has deposited its message onto the channel.
Similarly for receives.
If the order of raceacquire() and racerelease() is incorrect, the race
detector may fail to report some race conditions.
The fix is minimal from the point of view of Go. The fix does, however,
rely on a new function added to TSan:
https://reviews.llvm.org/D76322
This commit only affects execution when race detection is enabled.
Added two tests into `runtime/race/output_test.go`:
- `chanmm` tests for the issue addressed by this patch
- `mutex` is a test for inverted semaphores, which must not be broken

A hand-edited object file can have a symbol name that uses newline and
other normally invalid characters. The cgo tool will generate Go files
containing symbol names, unquoted. That can permit those symbol names
to inject Go code into a cgo-generated file. If that Go code uses the
//go:cgo_ldflag pragma, it can cause the C linker to run arbitrary
code when building a package. If you build an imported package we
permit arbitrary code at run time, but we don't want to permit it at
package build time. This CL prevents this in two ways.
In cgo, reject invalid symbols that contain non-printable or space
characters, or that contain anything that looks like a Go comment.
In the go tool, double check all //go:cgo_ldflag directives in
generated code, to make sure they follow the existing LDFLAG restrictions.

TestSetuidEtc() was failing sporadically on linux-ppc64. From the
three https://build.golang.org/ logs, it looked like the logged
errors could be associated with threads dying, but proc reads
were, in some way, racing with their demise.
Exploring ways to increase thread demise, revealed that races
of this type can happen on non-ppc64 systems, and that
os.IsNotExist(err) was not a sufficient error condition test
for a thread's status file disappearing. This change includes a
fix for that to.
The actual issue on linux-ppc64 appears to be tied to PID reaping
and reuse latency on whatever the build test environment is for
linux-ppc64-buildlet. I suspect this can happen on any linux
system, however, especially where the container has a limited PID
range.
The fix for this, limited to the test (the runtime syscall support
is unchanged), is to confirm that the Pid for the interrogated
thread's /proc/<TID>/status file confirms that it is still
associated with the test-process' PID.

This cl is a roll-forward of golang.org/cl/265758, which was rolled back
in golang.org/cl/268900. The changes made are removing cgofiles
from the list of files that are copied to objdir (because the cgofiles
themselves aren't actually provided to the compiler) and fixing test
cases to properly provide the overlay flag and to allow for paths with
backslashes (as in Windows).
The previous cl (golang.org/cl/262618) copied non-overlaid cgo files
to objdir, mostly to get around the issue that otherwise cgo-generated
files were written out with the wrong names (they'd get the base path
of the overlay file containing the replaced contents, instead of the
base path of the path whose contents are being replaced). So that CL
it would copy the files to objdir with the base path of the file
being replaced to circumvent that.
This CL changes cmd/go and cmd/cgo so that instead of copying
files, it passes the actual path of the file on disk either of
the original file (if it is not overlaid) or its replacement
file (if it is) as well as a flag --path_rewrite, newly added to
cmd/cgo, that specifies the actual original file path that corresponds
to the replaced files.

The Go 1.16 code freeze has recently started. This is a time to update
all golang.org/x/... module versions that contribute packages to the
std and cmd modules in the standard library to latest master versions.
Those versions have already gone through code review, and now they
will undergo additional testing during the upcoming freeze period.
If new issues in these dependencies are discovered, we have the freeze
period to address them. By the end of the freeze period, we will have
confidence that the Go 1.16 release and the dependency versions it has
selected are robust.
The dependency module versions that are selected in this commit are:

This is an extra variable available via 'go env', but not read from the
user's environment. It corresponds to the same string that
runtime.Version returns, assuming a program is built by the same version
of Go.
It's similar to the output of 'go version', but without the "go version"
prefix nor the "$GOOS/$GOARCH" suffix.
The main use case here is tools, which often use 'go env' to query basic
information about the installed Go tree. Its version was one missing
piece of information, which required an extra call to 'go version'
before this change.
Fixes#41116.

The previous cl (golang.org/cl/262618) copied non-overlaid cgo files
to objdir, mostly to get around the issue that otherwise cgo-generated
files were written out with the wrong names (they'd get the base path
of the overlay file containing the replaced contents, instead of the
base path of the path whose contents are being replaced). So that CL
it would copy the files to objdir with the base path of the file
being replaced to circumvent that.
This CL changes cmd/go and cmd/cgo so that instead of copying
files, it passes the actual path of the file on disk either of
the original file (if it is not overlaid) or its replacement
file (if it is) as well as a flag --path_rewrite, newly added to
cmd/cgo, that specifies the actual original file path that corresponds
to the replaced files.

https://man7.org/linux/man-pages/man2/copy_file_range.2.html#VERSIONS states:
A major rework of the kernel implementation occurred in 5.3. Areas
of the API that weren't clearly defined were clarified and the API
bounds are much more strictly checked than on earlier kernels.
Applications should target the behaviour and requirements of 5.3
kernels.
Rather than attempting to detect the file system for source and
destination files (which means two additional statfs syscalls) and skip
copy_file_range in case of known defects (e.g. CIFS -> CIFS), just
assume copy_file_range to be broken on kernels < 5.3.

AES-GCM based ciphers when they are adjacent to other AEAD ciphers.
Also updates a number of recorded openssl TLS tests which previously
only specified TLS 1.2 cipher preferences (using -cipher), but not
