formatZeroValue is currently only used when formatting return values for
statement completion. Per golang/go#40956, it must be possible to hit
this codepath with an invalid type.
In this case, the empty string seems like a reasonable value. Perhaps we
could do better, but fix the panic for now.

Fix completion in the following cases:
type foo struct{}
// now we offer "&foo" instead of "foo"
var _ *foo = fo<>{}
struct { f *foo }{
// now we offer "&foo" instead of "*foo"
f: fo<>{},
}
Composite literal type names are a bit special because they are part
of an arbitrary value expression rather than just a standalone type
name expression. In particular, they can be preceded by "&", which
affects how they relate to the surrounding context. The "&" doesn't
technically apply to the type name, but we must take it into account.
I made three changes to fix the behavior:
1. When we want to make a composite literal type name into a pointer,
we use "&" instead of "*".
2. Record if a composite literal type is already has a "&" so we don't
add it again.
3. Fix "var _ *foo = fo<>{}" to properly infer expected type of "*foo"
by not stopping at *ast.CompositeLit searching up AST path when the
position is in the type name (as opposed to within the curlies).

This change contains several improvements for progress reporting:
+ Consolidate the 'progressWriter' interface into the workDone
interface. Now all progress reporting should use workDone, and the
workDoneWriter struct is just an io.Writer adapter on top of
workDone.
+ Factor out the pattern of progress reporting, and use for all
asynchronous commands.
+ Make several commands that were previously synchronous async.
+ Add a test for cancellation when the WorkDone API is not supported.
+ Always report workdone progress using a detached context.
+ Update 'run tests' to use the -v option, and merge stderr and stdout,
to increase the amount of information reported.
+ Since $/progress reporting is now always run with a detached context,
the 'NoOutstandingWork' expectation should now behave correctly. Use
it in a few places.
A follow-up CL will improve the messages reported on command completion.

We now rank printf operand candidates according to the corresponding
formatting verb. We follow what fmt allows for the most part, but I
omitted some things because they are uncommon and would result in many
false positives, or didn't seem worth it to support:
- We don't prefer fmt.Stringer or error types for "%x" or "%X".
- We don't prefer pointers for any verbs except "%p".
- We don't prefer recursive application of verbs (e.g. we won't prefer
[]string for "%s").
I decided against sharing code with the printf analyzer. It was
tangled somewhat with go/analysis, and I needed only a very small
subset of the format parsing.
I tweaked candidate type evaluation to accommodate the printf hints.
We now skip expected type of "interface{}" when matching candidate
types because it matches everything and would always supersede the
coarser object kind checks.

When a signature doesn't name its params, we make up param
names when generating a corresponding func literal:
var f func(myType) // no param name
f = fun<> // completes to "func(mt myType) {}"
Previously we would abbreviate named types and fall back to "_" for
builtins or repeated names. We would require placeholders to be
enabled when using "_" so the user could name the param easily. That
left users that don't use placeholders with no completion at all in
this case.
I made the following improvements:
- Generate a name for all params. For builtin types we use the first
letter, e.g. "i" for "int", "s" for "[]string". If a name is
repeated, we append incrementing numeric suffixes. For example,
"func(int, int32)" becomes "func(i1 int, i2 int32").
- No longer require placeholders to be enabled in any case.
- Fix handling of alias types so the param name and type name are
based on the alias, not the aliasee.
I also tweaked formatVarType to qualify packages using a
types.Qualifier. I needed it to respect a qualifier that doesn't
qualify anything so I could format e.g. "http.Response" as just
"Response" to come up with param names.

example, let's say we want to Find References on fmt.Printf in the stdlib.
Before this CL, we'd force a new type check of the fmt package, then
find no references because nothing else would have been checked against
that new version.
While there may be some features that work better in the current regime,
I can't think of any, and we have no test coverage for them. So I'd

The GC-based cache has given us a number of problems. First, memory
leaks driven by reference cycles: the Go runtime cannot collect cycles
involving finalizers, which prevents us from writing natural code in
Bind callbacks. If we screw it up, we get a mysterious leak that takes a
long time to track down. Second, the behavior is generally mysterious;
it's hard to predict how long a value lasts, and harder to tell if a
value being live is a bug. Third, we think that it may be interacting
poorly with the GC, resulting in unnecessary memory usage.
The structure of the values we put in the cache is not actually that
complicated -- there are only 5 significant types: parse, typecheck,
analyze, parse mod, and analyze mod. Managing them manually should not
be conceptually difficult, and in fact we already do most of the work
in (*snapshot).clone.
In this CL the cache adds the concept of "generations", which function
as reference counts on cache entries. Entries are still global and
shared across generations, but will be explicitly deleted once no
generations refer to them. The idea is that each snapshot is a new
generation, and can inherit entries from the previous snapshot or leave
them behind to be deleted.
One obvious risk of this scheme is that we'll leave dangling references
to values without actually inheriting them across generations. To
prevent that, getting a value requires passing in the generation at
which it's being read, and an error will be returned if that generation
is dead.

In the previous implementation, we always created a default
value for each type in the struct or return statement in fillstruct
and fillreturns, respectively. Now, we try to find a variable in scope
that matches the expected type. If we find multiple matches, we choose
the variable that is named most similarly to the type. If we do not
find a variable that matches, we maintain the previous functionality.

Progress reporting has gotten complicated, and has had a couple bugs.
Factor out progress-related behavior to a new progressTracker type, and
use this to implement some unit tests.
Also rename some methods to remove stuttering, and reorganize the code
to be more logical.

Our WorkDone reporting was generating a random token for each unit of
work, even if a token was supplied by the client. Change this to use
the client token if it is non-empty, and skip the
workDoneProgress/create request.
After this change we can no longer rely on tokens being a string.
Update our progress tracking accordingly.

The gc annotation details code lens did build binaries during
diagnostics to the module root. When trying to enable details for a
main package in a sub directory, it failed since the output binary name
conflicted with the sub directory name.
Instead, specify output to the package directory during build to avoid
conflicts.

Now we downrank candidates that have already been used in other switch
cases. For example:
switch time.Now().Weekday() {
case time.Monday:
case time.<> // downrank time.Monday
}
It wasn't quite as simple as tracking the seen types.Objects.
Consider this example:
type foo struct {
i int
}
var a, b foo
switch 123 {
case a.i:
case <>
}
At <> we don't want to downrank "b.i" even though "i" is represented
as the same types.Object for "a.i" and "b.i". To accommodate this, we
track having seen ["a", "i"] together. We will downrank "a.i", but not
"b.i".
I applied only a minor 0.9 downranking when the candidate has already
been used in another case clause. It is hard to know what the user is
planning. For instance, in the preceding example the user could intend
to write "a.i + 1", so we mustn't downrank "a.i" too much.

We keep track of the N highest seen scores so we can quickly skip deep
completions not in the top N. Our logic for maintaining the top N list
wasn't quite right, resulting in certain cases where we would let
non-high scoring candidates through. I don't think the bug impacted
correctness.
