Now that .a files are no longer being preinstalled for
standard-library packages (#47257), tests that require the export data
from those files must have access to 'go list -export' in order to
generate and load export data from the Go build cache.
`go list -export` does not work without a Go compiler, so assume that
tests that need the 'go' command also need the compiler.
This may cause the tests currently failing on the android-.*-emu
builders to instead be skipped, since the test harness does not copy
the compiler to the execution environment.
For golang/go#47257.

The result of type checking is a package (types.Package), type
annotations on syntax trees (types.Info), and zero or more type
errors (types.Error). Hitherto we had assumed that analyzers don't
need access to type errors, but in fact it turns out to be useful:
for example, analyzers can look at broken code and suggest quick
fixes to repair the mistakes.
This change adds a Pass.TypeErrors field that holds the errors
produced during type checking. It may be non-nil only when the
Analyzer.RunDespiteErrors flag was enabled. Similarly, it adds
a TypeErrors field to go/packages.Package.
(The existing Packages.Error field loses important details.)
Gopls was already using analyzers in this way, (ab)using its privileged
position in the x/tools repo. This change removes the need for such hacks.
We expect that all analysis drivers that support RunDespiteErrors will
in due course populate the Pass.TypesErrors field. This change updates
the go/packages-based driver to do so; no changes were needed to
unitchecker since it does not support RunDespiteErrors.
In the meantime, not populating this field is not expected to cause
any compatibility problems.

The only explanation I can think of for the failure in
https://go.dev/issue/49387#issuecomment-1303979877 is that maybe the
idle timeout started as soon as conn1 was closed, without waiting for
conn2 to be closed. That might be possible if the connection returned
by Dial was still in the server's accept queue, but never actually
accepted.
To eliminate that possibility, we can send an RPC on that connection
and wait for a response, as we already do with conn1. Since the conn1
RPC succeeded, we know that the connection is non-idle, conn2 should
be accepted, and the request on conn2 should succeed unconditionally.

Prior to this CL we already shut down a jsonrpc2_v2.Conn when its
Reader breaks, which we expect to be the common shutdown path.
However, with certain kinds of connections (notably those over
stdin+stdout), it is possible for the Writer side to fail while
the Reader remains working.
If the Writer has failed, we have no way to return the required
Response messages for incoming calls, nor to write new Request
messages of our own. Since we have no way to return a response,
we will now mark those incoming calls as canceled.
However, even if the Writer has failed we may still be able to read
the responses for any outgoing calls that are already in flight. When
our in-flight calls complete, we could in theory even continue to
process Notification messages from the Reader; however, those are
unlikely to be useful with half the connection broken. It seems more
helpful — and less surprising — to go ahead and shut down the
connection completely when it becomes idle.
This is a redo of CL 446315, with additional fixes for bugs exposed on
the -race builders and some extra code cleanup from the process of
diagnosing those bugs.
Updates golang/go#46520.
Updates golang/go#49387.

This CL includes some clarifications while trying to
understand the performance of the initial workspace load
and analysis. No significant behavior changes.
Server.diagnose:
- Factor the four copies of the logic for dealing
with diagnostics and errors.
- Make the ActivePackages blocking step explicit.
Previously mod.Diagnostics would do this implicitly,
making it look more expensive than it is.
Server.addFolders:
- eliminate TODO. The logic is not in fact fishy.
- use informative names and comments for WaitGroups.
- use a channel in place of a non-counting WaitGroup.
Also, give pkg a String method.

Rename (*connection).AddFile to openFile, which is more accurate, and
fix a deadlock resulting from holding a Client lock while issuing a
Server request.

Fix a panic during completion on variables of type *error. As a
predeclared type, the error type has nil package. Fix the crash
resulting from this oversight, as well as a related crash in the tests
analyzer, from which the new completion code was adapted.

Simplify the api-diff implementation to use `go run` and cmp.Diff. The
latter is more maintainable and produces more readable output, due to
supporting line diffs for multi-line strings.

Memory profiles show heavy allocation for the stack
and the function closure of FindDeclAndField.
This change moves both outside the loop, reducing
this function's fraction of allocation from 6.7%
before to 5.0% after, and reducing running time
by 3-7% on these benchmarks.
