`go build` has chosen the last element of the package import path
as the default output name when -o option is given. That caused
the output of a package build when the module root is the major
version component such as 'v2'.
A similar issue involving `go install` was fixed in
https://golang.org/cl/128900. This CL refactors the logic added
with the change and makes it available as
internal/load.DefaultExecName.
This CL makes 'go test' to choose the right default test binary
name when the tested package is in the module root. (E.g.,
instead of v2.test, choose pkg.test for the test of 'path/pkg/v2')
Fixes#27283.

This reduces the number of extra bounds check hints we need to

We now produce:

This internally exported function allowed merging environment variable

It seems to date all the way back to 2013.
However, since CL 37586 in early 2017, os/exec has already taken care of
deduplicating environment variable lists. Thus, it's unnecessary for
cmd/go to take care of that before calling exec.Cmd.Start.
Moreover, because os/exec will deduplicate the list in any case, we're
adding extra work in all these scenarios.
Finally, remove an unnecessary addition of GOROOT= in internal/tool.
cfg.OrigEnv may not have the correct GOROOT set up, but os.Environ does;
cmd/go's main function makes sure of that.

Most of the decoding time is spent in the first Decode loop, since the
rest of the function only deals with the few remaining bytes. Any
unnecessary work done in that loop body matters tremendously.
One such unnecessary bottleneck was the use of the enc.decodeMap table.
Since enc is a pointer receiver, and the field is used within the
non-inlineable function decode64, the decoder must perform a nil check
at every iteration.
To fix that, move the enc.decodeMap uses to the parent function, where
we can lift the nil check outside the loop. That gives roughly a 15%
speed-up. The function no longer performs decoding per se, so rename it.
While at it, remove the now unnecessary receivers.
An unfortunate side effect of this change is that the loop now contains
eight bounds checks on src instead of just one. However, not having to
slice src plus the nil check removal well outweigh the added cost.
The other piece that made decode64 slow was that it wasn't inlined, and
had multiple branches. Use a simple bitwise-or trick suggested by Roger
Peppe, and collapse the rest of the bitwise logic into a single
expression. Inlinability and the reduced branching give a further 10%
speed-up.
Finally, add these two functions to TestIntendedInlining, since we want
them to stay inlinable.
Apply the same refactor to decode32 for consistency, and to let 32-bit
architectures see a similar performance gain for large inputs.

This change makes it possible the runtime-integrated network poller and
APIs in the package internal/poll to report an event scanning error on a
read event.
The latest Go releases open up the way of the manipulation of the poller
for users. On the other hand, it starts misleading users into believing
that the poller accepts any user-configured file or socket perfectly
because of not reporting any error on event scanning, as mentioned in
issue 30426. The initial implementation of the poller was designed for
just well-configured, validated sockets produced by the package net.
However, the assumption is now obsolete.

Lines with single cells prompt a flush. Unfortunately, a call to
Writer.Flush also means two defers, which is an expensive operation to
do if many lines consist of single cells.
This is common when formatting code with aligned comments. Most lines
aren't going to have any comments at all, so the performance hit is
going to be noticeable.
The Write method already has a "defer handlePanic" of its own, so we
don't need to worry about panics leaking out. The error will now mention
"Write" instead of "Flush" if a panic is encountered during that nested
flush, but arguably that's a good thing; the user called Write, not
Flush.
For the reset call, add a non-deferred call as part of flushNoDefers, as
that's still necessary. Otherwise, the exported Flush method still does
a "defer b.reset".
The current tabwriter benchmarks are unaffected, since they don't
contain many single-cell lines, and because lines are written one at a
time. For that reason, we add a benchmark which has both of these
characteristics.

This CL documents the new binary and octal integer literals,

separators for all number literals in the spec.
Added empty lines between abutting paragraphs in some places
(a more thorough cleanup can be done in a separate CL).
A minor detail: A single 0 was considered an octal zero per the
syntax (decimal integer literals always started with a non-zero
digit). The new octal literal syntax allows 0o and 0O prefixes
and when keeping the respective octal_lit syntax symmetric with
all the others (binary_lit, hex_lit), a single 0 is not automatically
part of it anymore. Rather than complicating the new octal_lit syntax
to include 0 as before, it is simpler (and more natural) to accept
a single 0 as part of a decimal_lit. This is purely a notational
change.

Before this CL, uid/gid mapping was always set up from the parent
process, which is a privileged operation.
When using unprivileged user namespaces, a process can modify its
uid/gid mapping after the unshare(2) call (but setting the uid/gid
mapping from another process is NOT possible).
Fixes#29789

The android emulator builders is running out of space after CL 165797
copied most of GOROOT to the device.
The pkg directory is by far the largest, so only include what seems
necessary to build the x/ repositories: pkg/android_$GOARCH and
pkg/tool/android_$GOARCH.
While here, rename the device root directory to match the exec
wrapper name and make sure the deferred cleanups actually run before
os.Exit.
Hopefully fixes the emulator builders.

This also updates the vendored-in versions of several packages: 'go
mod vendor' selects a consistent version of each module, but we had
previously vendored an ad-hoc selection of packages.
Notably, x/crypto/hkdf was previously vendored in at a much newer
commit than the rest of x/crypto. Bringing the rest of x/crypto up to
that commit introduced an import of golang.org/x/sys/cpu, which broke
the js/wasm build, requiring an upgrade of x/sys to pick up CL 165749.

This change preserves the maximum versions from cmd/vendor/vendor.json
where feasible, but bumps the versions of x/sys (for CL 162987) and
x/tools (for CL 162989 and CL 160837) so that 'go test all' passes in
module mode when run from a working directory in src/cmd.
A small change to cmd/vet (not vendored) was necessary to preserve its
flag behavior given a pristine copy of x/tools; see CL 162989 for more
detail.
This change was generated by running 'go mod vendor' at CL 164622.
