Completion could be slow due to calls to astutil.PathEnclosingInterval
for every candidate during formatting. There were two reasons we
called PEI:
1. To properly render type alias names, we must refer to the AST
because the alias name is not available in the typed world.
Previously we would call PEI to find the *type.Var's
corresponding *ast.Field, but now we have a PosToField cache that
lets us jump straight from the types.Object's token.Pos to the
corresponding *ast.Field.
2. To display an object's documentation we must refer to the AST. We
need the object's declaring node and any containing ast.Decl. We
now maintain a special PosToDecl cache so we can avoid the PEI call
in this case as well.
We can't use a single cache for both because the *ast.Field's position
is present in both caches (but points to different nodes). The caches
are memoized to defer generation until they are needed and to save
work creating them if the *ast.Files haven't changed.
These changes speed up completing the fields of
github.com/aws/aws-sdk-go/service/ec2 from 18.5s to 45ms on my laptop.

Several fixes related to GOPRIVATE handling and links:
+ In Go source, fix links matching GOPRIVATE for external modules.
Previously, in these cases we'd try to match <mod>@v1.2.3/<suffix>,
which wasn't the correct input into the GOPRIVATE matching algorithm.
+ Similarly check GOPRIVATE for go.mod require statement hovers.
+ Likewise, for documentLink requests (both mod and source).
+ Move the existing hover regtest to link_test.go, and expand to cover
all these cases.
Along the way, I encountered a couple apparent bugs, which I fixed:
+ Correctly handle the case where there is only one require in a go.mod
file. This was exercised by the regtest, so took some debugging.
+ Only format links [like](this) if the requested format is actually

We use file identities pervasively throughout gopls. Prior to this
change, the identity is the modification date of an unopened file, or
the hash of an opened file. That means that opening a file changes its
identity, which causes unnecessary churn in the cache.
Unfortunately, there isn't an easy way to fix this. Changing the
cache key to something else, such as the modification time, means that
we won't unify cache entries if a change is made and then undone. The
approach here is to read files eagerly in GetFile, so that we know their
hashes immediately. That resolves the churn, but means that we do a ton
of file IO at startup.
Incidental changes:
Remove the FileSystem interface; there was only one implementation and
it added a fair amount of cruft. We have many other places that assume
os.Stat and such work.
Add direct accessors to FileHandle for URI, Kind, and Version. Most uses
of (FileHandle).Identity were for stuff that we derive solely from the
URI, and this helped me disentangle them. It is a *ton* of churn,
though. I can revert it if you want.

Assigning a slice to the appendage of itself is common and tedious
enough to warrant a special case completion candidate. We now offer
smarter "append()" candidates:
var foo []int
foo = app<> // offer "append(foo, <>)"
fo<> // offer "foo = append(foo, <>)"
The latter is only offered if the best completion candidate is a
slice. It is inserted as the second-best candidate because it seems
impossible to avoid annoying false positives if it is ranked first.
I added a new debug option to disable literal completions. This was to
clean up some test logic that was disabling snippets for all tests

This change moves as much view initialization code into the

Also, the `go env` variables that are collected at inconsistent times

is recreated if the environment changes.
I had originally hoped that the initial call to `go env` and the
-modfile detection could become part of this parallel initialization as
well, but you can't create a *packages.Config until the temporary
modfile has been set up, so it still makes sense to do that on view
create. This is, however, the reasoning behind the refactorings in
the -modfile detection in this CL. The main changes are a few renamings
and a split between snapshot.ModFiles and view.modFiles to maximize the

We now support taking the address of objects to make better completion
candidates. For example:

var p *int = <> // now you get a candidate for "&i"
This required that we track addressability better, particularly when
searching for deep candidates. Now each candidate knows if it is
addressable, and the deep search propagates addressability to child
candidates appropriately.
The basic propagation logic is:
- In-scope *types.Var candidates are addressable. This handles your
basic "foo" variable whose address if "&foo".
- Surrounding selector is addressable based on type checker info. This
knows "foo.bar.<>" is addressable but "foo.bar().<>" isn't
- When evaluating deep completions, fields after a function call lose
addressability, but fields after a pointer regain addressability. For
example, "foo.bar()" isn't addressable, but "foo.bar().baz" is
addressable if "bar()" returns a pointer.

"bar.go" doesn't import "context" yet, so normally you need to first import
"context" through whatever means before you get completion items from "context".
Now we notice that the expected type's package hasn't been imported yet and give
deep completions from "context".
Another use case is with literal completions. Consider:
-- foo.go --
import "bytes"
func doSomething(buf *bytes.Buffer) {}
-- bar.go--
doSomething(<>)
Now you will get a literal completion for "&bytes.Buffer{}" in "bar.go" even
though it hasn't imported "bytes" yet.
I had to pipe the import info around a bunch of places so the import is added
automatically for deep completions and literal completions.

Now that we are using the memoize package to cache analysis results, we
can use that cache for suggested fixes.

This change effectively reverts CL 202039. This CL was a mistake, as it
creates a cycle. Snapshots hold CheckPackageHandles, which in turn hold
pkgs.

A package really should always be associated with its snapshot rather
than its view. This eliminates some extra parameters in a few utility
functions.

Now we offer completion candidates for labels when completing "break",
"continue", and "goto" statements. We are reasonably smart about
filtering unusable labels, except we don't filter "goto" candidates
that jump across variable definitions.
Fixesgolang/go#33987.

This change does not complete the work to handle snapshots correctly,
but it does implement the behavior of re-building the snapshot on each
file invalidation.
It also moves to the approach of caching the FileHandles on the snapshot,
rather than in the goFile object, which is now not necessary.
Finally, this change shifts the logic of metadata invalidation into the
content invalidation step, so there is less logic to decide if we should
re-load a package or not.

Parse errors need to be treated separately from actual errors when
parsing a file. Parse errors are treated more like values, whereas
actual errors should not be propagated to the user. This enables us to
delete some of the special handling for context.Canceled errors.

We had too many options for functions to use to get type information for
a package. Now we stick with having one option to get the check package
handles, and then the caller can refine the results as needed.
