4a0a2b33df errors, fmt: add support for wrapping multiple errors
An error which implements an "Unwrap() []error" method wraps all the
non-nil errors in the returned []error.

We replace the concept of the "error chain" inspected by errors.Is
and errors.As with the "error tree". Is and As perform a pre-order,
depth-first traversal of an error's tree. As returns the first
matching result, if any.

The new errors.Join function returns an error wrapping a list of errors.

The fmt.Errorf function now supports multiple instances of the %w verb.

For #53435.

2ff5fbfbd4 cmd/compile: limit goroutine count to parallelism
When the compiler crashes, it is not uncommon to see many hundreds
of goroutines all blocked waiting their turn to be one of the nWorkers
goroutines that is allowed to run. All these goroutine stacks are not a
terribly efficient use of memory, and they also make the crash dumps
hard to read.

Introduce a manager goroutine to hand out work to at most nWorker
goroutines, maintaining pending work in a local slice, rather than
having all those blocked goroutines hanging around waiting to run.

9861e8b2fd cmd/{cover,go}: avoid use of os.PathListSeparator in cmd/cover flag
Rework the mechanism for passing a list of output files from cmd/go to
cmd/cover when running new-style package-scope coverage
instrumentation (-pkgcfg mode). The old scheme passed a single string
with all output files joined together with os.PathListSeparator, but
this scheme is not viable on plan9, where strings containing the
separator character are not permitted when running exec.Command().
Instead, switch cmd/cover to use an arguments file (a file containing
a list of names) to specify names of instrumented output files. This
fixes the cmd/cover test failures on the plan9 builders.

Updates #51430.

e22af33b48 go/types, types2: more concise error messages for cycle errors
If a cycle has length 1, don't enumerate the single cycle entry;
instead just mention "refers to itself". For instance, for an
invalid recursive type T we now report:

	invalid recursive type: T refers to itself

instead of:

	invalid recursive type T
		T refers to
		T

Adjust tests to check for the different error messages.

ecd112c0d1 runtime/coverage: apis to emit counter data under user control
Add hooks/apis to support writing of coverage counter data and
meta-data under user control (from within an executing "-cover"
binary), so as to provide a way to obtain coverage data from programs
that do not terminate. This patch also adds a hook for clearing the
coverage counter data for a running program, something that can be
helpful when the intent is to capture coverage info from a specific
window of program execution.

Updates #51430.

f2ee341468 cmd{cover,covdata,go}: better coverage for tests that build tools
Some of the unit tests in Go's "cmd" tree wind up building a separate
copy of the tool being tested, then exercise the freshly built tool as
a way of doing regression tests. The intent is to make sure that "go
test" is testing the current state of the source code, as opposed to
whatever happened to be current when "go install <tool>" was last run.

Doing things this way is unfriendly for coverage testing. If I run "go
test -cover cmd/mumble", and the cmd/mumble test harness builds a
fresh copy of mumble.exe, any runs of that new executable won't
generate coverage data.

This patch updates the test harnesses to use the unit test executable
as a stand-in for the tool itself, so that if "go test -cover" is in
effect, we get the effect of building the tool executable for coverage
as well. Doing this brings up the overall test coverage number for
cmd/cover quite dramatically:

before change:

  $ go test -cover .
  ok  	cmd/cover	1.100s	coverage: 1.5% of statements

after change:

  $ go test -cover .
  ok  	cmd/cover	1.299s	coverage: 84.2% of statements

Getting this to work requires a small change in the Go command as
well, to set GOCOVERDIR prior to executing a test binary.

Updates #51430.

223a563f58 os/exec: refactor goroutine error reporting
Use a separate channel to report the final error of the copying
goroutines, receiving a value only when all of the copying goroutines
have completed. In a followup change (CL 401835), that will allow
waiters to select on goroutine completion alongside other events (such
as Context cancellation).

Also mildly refactor the watchCtx helper method so that its structure
better matches what will be needed to implement WaitDelay.

For #50436.

This CL removes some opcode placeholders that do not correspond
to any existing instructions and hence create confusion. Some
instructions that are no longer valid like LDMX are also removed.
Any references to this instruction in ISA 3.0 are considered
as documentation errata.

53773a5d08 cmd/go: support new hybrid coverage instrumentation
If GOEXPERIMENT=coverageredesign is in effect, introduce a new
top-level '-cover' option to "go build" to turn on new-style hybrid
code coverage instrumentation. Similarly, use the new instrumentation
for "go test -cover".

The main effects of "-cover" under the hood are to instrument files at
the package level using cmd/cover and to pass additional options to
the compiler when building instrumented packages.

The previous workflow for "go tool -cover mypkg" would expand to a
series of "go tool cover" commands (one per file) followed by a single
package compilation command to build the rewritten sources.

With the new workflow, the Go command will pass all of the Go files in
a package to the cover tool as a chunk (along with a config file
containing other parameters), then the cover tool will write
instrumented versions of the sources along with another "output"
config with info on coverage variable names for the the compiler. The
Go command will then kick off the compiler on the modified source
files, also passing in the config file generated by cmd/cover.

Updates #51430.

Refactor references to "a.Package" in Builder.build to be consistent,

is just intended to make the code more readable/consistent (since
prior to this point we had a random mix of "p" and "a.Package").

5f18e46328 cmd/cover: add hybrid instrumentation mode
Add a new mode of coverage instrumentation that works as a hybrid
between purely tool-based and purely compiler-based. The cmd/cover
tool still does source-to-source rewriting, but it also generates
information to be used by the compiler to do things like marking
meta-data vars as read-only.

In hybrid mode, the cmd/cover tool is invoked not on a single source
file but on all the files in a package, and is passed a config file
containing the import path of the package in question, along with
other parameters needed for the run. It writes a series of modified
files and an output config file to be passed to the compiler when
compiling the modified files.

Not completely useful by itself, still needs a corresponding set of
changes in the Go command and in the compiler.

Updates #51430.

87db4ffada runtime/coverage: runtime routines to emit coverage data
This patch fleshes out the runtime support for emitting coverage data
at the end of a run of an instrumented binary. Data is emitted in the
form of a pair of files, a meta-out-file and counter-data-outfile,
each written to the dir GOCOVERDIR. The meta-out-file is emitted only
if required; no need to emit again if an existing meta-data file with
the same hash and length is present.

Updates #51430.
