If a context was canceled during load, only report it as a critical
error if the load actually failed.
Along the way, simplify evaulation of the critical error to use a switch
statement.
Also await IWL in the second Env used in shared regtests. Presumably it
is this Env that is being shutdown prior to IWL, triggering the
panicking code-path from golang/go#47030. I wasn't able to reproduce,
but all panics are occurring in regtest/misc, and this seems highly
plausible.

This cuts the running time for 'go test -short ./go/packages' by about
50% by skipping the tests that run in GOPATH mode.
All of the tests are still run when the -short flag is not set, so the
longtest builders should still report any GOPATH-mode regressions, and
the faster short tests should improve turnaround times (and resource
usage and associated test flakiness) on the non-longtest builders.

TestDebouncer inherently depends on the timing of events. Specifically,
it can fail if the pause between two subsequent events is more than the
debouncing delay.
When this has proved flaky in the past I just increased the debouncing
delay. However, tests are still occasionally flaking. Rather than just
increase the delay arbitrarily, attempt to make the test more robust by
retrying up to three times if the base assumption (that goroutines are
scheduled within a reasonable amount of time) is not met.

Gopls's serial processing of didChangeWatchedFile notifications has
historically been a pain point for clients that don't batch file events,
when branch switching or running go generate.
It's "not that tricky" for us to debounce and batch up watched file
notifications on our end, so this CL introduces this functionality as a
new experimental setting. Truth be told it ended up being harder than
expected, due to (1) our requirement for regtests to be able to
determine when diagnostics have completed, and (2) our reliance on
jsonrpc2 for sequencing changes to the server.
To address (1), I factored out the actual processing of change
notifications into a separate method (thus increasing our surprisingly
long chain of method calls). To address (2), I guarded the processing of
file changes with a mutex.
I also guarded some places where views and snapshots were accessed in
potentially racy ways. Our interaction with session.views was rather
complicated, so I had to switch session.viewsMu to a RWMutex.
Add this to the experimental regtest mode, and more generally enable all
experimental features in this mode, rather than just the experimental
workspace module.

The new Binder API admits a nice abstraction that can help make the

middleware that can instrument all aspects of the connection lifecycle.
In this CL, this pattern is used to decouple the server handshake from
the actual forwarding setup. Later CLs will implement additional

Retrying CL 271477, this time with parts of CL 322650 incorporated.
This CL moves to a model where we don't automatically delete invalidated
metadata, but rather preserve it and mark it invalid. This way, we can
continue to use invalid metadata for all features even if there is an
issue with the user's workspace.
To keep track of the metadata's validity, we add an invalid flag to
track the status of the metadata. We still reload at the same rate--the
next CL changes the way we reload data.
We also add a configuration to opt-in (currently, this is off by
default).
In some cases, like switches between GOPATH and module modes, and when a
file is deleted, the metadata *must* be deleted outright.
Also, handle an empty GOMODCACHE in the directory filters (from a
previous CL).

In the presence of an import cycle, packages.Load will exclude the
problematic import from Package.Imports. This missing edge means that we
wouldn't correctly invalidate broken package metadata when a problematic
import is deleted. We also weren't treating import deletion as a change
that could invalidate metadata.
Fix this by invalidating any broken packages when an import path is
deleted, anywhere. This could be overly coarse, but there are various
problems with trying to do better.
Also change cycle errors from TypeError to ListError, as this
categorization was misleading.

Use the typeparams helper package to fix AST rewriting in go/ast/astutil
when encountering the new ListExpr type.
This is liable to break in the future when the go/ast API changes, but
at least it will be easy to find by virtue of using internal/typeparams.

The propagation consists of two steps. First, VTA graph is converted to
a DAG by computing SCCs (resolving any graph loops) and then types and
higher-order functions are propagated through the DAG.
The results of this propagation are used in the final step to create a
call graph. That CL comes after this one.

For array, slice, maps and chan candidates, we now support
transforming them to their element type in completions. For example:
var m map[string]int
var _ int = m<>
At <> we complete to "m[]" because we see that the map value type
matches our expected type.

Now we search up to three levels for candidate modifiers. For example,
we can now complete "foo" to "foo()()" (double invocation).
Granted this is rarely useful, but it generalizes and simplifies the
searching we did for dereference modifiers.

"type mod" refers to agglutinative expressions such as dereference
"*", invocation "()", and slicing "[:]". When considering an object as
a completion candidate, we check whether applying a type mod would
make it a better candidate.
Previously we tracked the type mods we wanted to apply to a candidate
by setting bool fields. Now instead we keep a slice of the type mods.
This has two main advantages:
- The mods are now ordered which will allow us to format candidates
properly when the same mods can appear in different order (e.g.
"<-*foo" or *<-foo").
- We can now record any mod multiple times allowing for "<-<-foo" or
"foo()()".
I changed the formatting code to always create a snippet object since
that made things simpler. I had to tweak a few snippet helper methods
to accept a snippet argument rather than creating a new snippet.
This commit's only functional change is that we no longer show any
type mods in candidate labels. For example, the user will now see
"foo" in the completion popup instead of "*foo". Showing the operators
adds noise to the candidate list, and we didn't display them
consistently.
Updates golang/go#46045.

When choosing variable names, extract makes sure that the chosen
name does not conflict with any existing variables. By avoiding these
conflicts, we may actually have a conflict with the other names we
are choosing. This change removes this conflict by sending the next
index to use as the suffix of the function name.
