TestIssue64958 takes a while, so it's not worth running both without
and with -check flag. The others are fast, but there's still no good
reason to run anything but TestCheck when the -check flag is on.

So import_ must have returned an error, making pkg nil. Show that error.
Also do the same at the other calls to import_.

This case recently started happening on the builders.
The synctest experiment was recently enabled for some targets (CL 642422).
This caused the list of standard packages to include testing/synctest.
However, BenchmarkAll tests for all configurations;
some did not include testing/synctest. That caused the test to crash.

Doing this because the slices functions are slightly faster and
slightly easier to use. It also removes one dependency layer.
We did this outside of bootstrap tools in CL 587655.
Now that the bootstrap compiler is 1.22, we can do this in more code.

The order of emitting named type and type aliases in the `Walker`'s
`emitType` function is inverted. When the type alias references a basic
type, this causes a panic as the type assertion on `*types.Named` fails.
This change reorders the logic such that type aliases are emitted prior
to this type assertion.
Fixes#64958

This makes cmd/api no longer an importable package.
In CL 453258 I forgot that there was no direct prohibition
on importing packages from cmd - we just rely on the
fact that cmd/* is all package main and everything else
is cmd/internal.
Fixes#62069.

While here, warm up the go list cache in parallel, which reduces the

This makes 'go test -list cmd/api' work, and fixes an infinite
recursion via testenv.HasExec that would otherwise occur.
As of CL 488076, testenv.HasExec tries to re-exec the test
executable using -list to suppress running the tests, which
produces a fork bomb if TestMain itself calls HasExec.
For this test, it turns out that the HasExec check is redundant
anyway: if we can exec 'go build', we can certainly exec programs in
general too.

We no longer use the optional parameter to compareAPI.
We now always set allowAdd to false.
(Except in tests, making them less useful than they could be.)
Flags and parsing their value are no more.
Remove all the unused functionality and update test cases so they're
closer to what the API checker does when it runs for real. Order the
features, required, exception variables and fields more consistently.
For #43956.

Deprecating an API creates notices that go out to potentially
millions of Go developers encouraging them to update their code.
The choice to deprecate an API is as important as the choice to
add a new API. We should track those and make them explicit.
This will also ensure that deprecations go through proposal review.

No one ever runs 'go tool api', because the invocation
has gotten unwieldy enough that it's not practical.
And we don't support it as a standalone tool for other
packages - it's not even in the distribution.
Making it an ordinary package test lets us invoke it
more easily from cmd/dist (as go test cmd/api -check)
and avoids the increasingly baroque code in run.go to
build a command line.
Left in cmd/api even though it's no longer a command
because (1) it uses a package from cmd/vendor and
(2) it uses internal/testenv. Otherwise it could be misc/api.
Fixes#56845.
