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).

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.

inserting it again with the completion. Fix by propagating
modifiers.
2. The candidate formatting responsible for adding "..." had over

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.

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.

Fix a minor completion ranking issue:
foo := func(int, int) {}
foo(123, <>)
Previously we were preferring "foo()" at "<>" even though it can't be
used. We mistakenly thought we were completing the first param because
the *ast.CallExpr appears to only have a single param.

The gc_details command, which shows the gc compiler's decisions, can
produce thousands of diagnostics for a package. New gopls options
'noBounds', 'noEscape', 'noInline', 'noNilcheck' will suppress diagnostics
of less interest to the user. These are in a new 'annotations' section
parallel to 'codelens' or 'analyses'.

snapshot.View().Session().Cache().FileSet() has been driving me crazy
for a while. Add it to snapshot. Along the way, discover that the Cache
interface is now totally unused and delete it.
I also changed a bunch of View arguments to Snapshot while I was in the
area.

This CL addresses completion prefix not being overwritten for completion
in comments for exported variables/functions/types etc. Instead of
setting the surrounding range as cursor position, we expand out from
cursor instead to replace the word we're currently on.

FileHandle currently includes LSP-level information about Version and
Session. That's dangerous, because the cache operates in terms of
URIs and content only -- we explicitly want to share results across
sessions and versions if they happen to be the same.
Split the LSP information into separate types, VersionedFileHandle and
VersionedFileIdentity.

To manually collect cache entries, we need to know when a snapshot is
idle. Add a reference count in the form of a WaitGroup and keep track of
its uses. The pattern is that any time a snapshot is returned, it comes
with a release function that decrements the ref count.
Almost all uses of a snapshot originate in a user-facing request,
handled in beginFileRequest. There it's mostly an exercise in passing
Snapshots around instead of Views.
In the other places I took the path of least resistance. For file
modifications I tried to minimize the amount of code that needed to deal
with snapshots. For diagnostics I just acquired the snapshot at the
diagnostics call.
