In order for regtests to wait until file diagnostics are complete,
instrument diagnostics with verbose WorkDone reporting. In order for
this to be granular enough for use, the modification source needed to be
threaded through to the didModifyFiles function (which is where the
diagnostic goroutine is spun off).
A new expectation is added: CompletedWork, to allow specifying that a
specific work item has been completed. The problem with using
NoOutstandingWork was that it required a continuous chain of work to
prevent the regtest from succeeding when the bug was present, meaning
that by the time we have sent the didChange notification successfully
the server must have started work on its behalf. This was inherently
racy, and too tricky to get right.
Additionally, a couple bugs are fixed:
- EmptyDiagnostics is corrected to account for the case where we have
received zero diagnostics for a given file.
- A deadlock is fixed in Await when expectations are immediately met.

This change is the first step in handling golang/go#38136. Instead of
creating multiple diagnostic reports for type error analyzers, we add
suggested fixes to the existing reports. To match the analyzers for
FindAnalysisError, we add an ErrorMatch function to source.Analyzer.
This is not an ideal solution, but it was the best one I could come up
with without modifying the go/analysis API. analysisinternal could be
used for this purpose, but it seemed to complicated to be worth it, and
this is fairly simple. I think that go/analysis itself might need to be
extended for type error analyzers, but these temporary measures will
help us understand the kinds of features we need for type error
analyzers.
A follow-up CL might be to not add reports for type error analyzers
until the end of source.Diagnostic, which would remove the need for the
look-up.

This change moves to our ultimate approach of diagnostics the snapshot
on every file change, instead of carefully picking which files and
packages to diagnose. Analyses are shown for packages whose files are
open in the editor. Reverse dependencies are no longer needed for
source.Diagnostics because they will be invalidated when the snapshot is
cloned, so diagnosing the entire snapshot will bring them up to date.
This even works for go.mod files because all of workspace-level `go list`s
will be canceled as the user types, and then we trigger an uncancellable
go/packages.Load when the user saves. There is still room for improvement
here, but it will require much more careful invalidation of metadata for
go.mod files.

The initial workspace load was happening when a view was created, in serial.
It should really just be kicked off in a separate goroutine once we create a
new view. Implementing this change required some other significant changes,
particularly the additional work being done by the WorkspacePackageIDs
method.
Some other changes had to be made while debugging. In particular, the
modification to the circular dependencies test was a consequence of
golang/go#36265.

There were a few cases that we were missing when caching diagnostics.
The first was caching empty diagnostics from the initial workspace load,
so we were resending old empty diagnostics. The second missing case was
resending diagnostics for the same version of a file.
Fixesgolang/go#36340.

This change eliminates the extra step of calling GetFile on the view and
getting the FileHandle from the snapshot. It also eliminiates the
redundant source.File type. Follow up changes will clean up the file
kind handling, since it still exists on the fileBase type.

Cache delivered diagnostics on the server so that we can determine if
they should be resent. To be careful about this, we only reuse cached
diagnostics if they are for a greater version, or if we don't know
the file's version and it is unchanged.

This change is the next step in unification of text synchronization
methods. The logic really belongs in the internal/lsp/cache package
rather than the internal/lsp package.
Pulled out a function to run diagnostics on a file (diagnostics are still
run async).

We don't distinguish between genuine errors and context cancellation in
diagnostics, which often results in superfluous logging of these errors.
Avoid spamming the logs with them by checking.
Also, remove the logic for sending undelivered diagnostics. It's a relic
of old bugs and isn't useful.

Previously, we returned CheckPackageHandles when creating a new view.
Now, return the view's snapshot. Also, add a WorkspacePackageIDs
function in order to run diagnostics on them.

Running staticcheck on the entire workspace causes a slowdown, and most
likely users don't want to see staticcheck reports for every
subdirectory of their workspace. Only run staticcheck on open files.
Also, fixed a staticcheck warning that showed up along the way. Filed
golang/go#35718 to remind ourselves to fix all of the staticcheck warnings
that showed up when we ran gopls with staticcheck on x/tools.
Finally, made sure that we don't send empty diagnostics when diagnosing
the snapshot on start-up, as that is not necessary.
