not want all objects that have position token.NoPos to be matched
when we are looking for references for this object, so we need to

We err on the side of refreshing package metadata if something goes
wrong getting a file's AST, but we don't want to refresh in the case
of context cancellation. Now we check for that error explicitly.
In particular, I noticed that completions would stop working when
typing quickly. Refreshing the metadata triggers "go list" calls which
can take a long time in certain cases.

The first deadlock involved differing mutex acquisition order in two
code paths:
1. loadParseTypecheck() holds the "mcache" mutex then eventually
acquires the "handleMu" file mutex.
2. (*goFile).invalidateContent() acquires the "handleMu" mutex first and
then the "mcache" mutex.
Fix by changing the acquisition order in invalidateContent().
The second deadlock involved the file watcher. The two code paths
involved were:
1. (*goFile).GetPackages() holds the view mutex and eventually calls
(*WatchMap).Watch, which acquires the watcher mutex.
2. (*session).openOverlay acquires the watcher mutex as it triggers a
file's callbacks, and then the callback
"(*goFile).invalidateContent" acquires the view mutex.
Fix by not holding the watcher mutex as we invoke the callbacks.

Add some extra smarts when evaluating untyped constants as completion
candidates. Previously we called types.Default() on the expected type
and candidate type, but this loses the untypedness of an untyped
constant which prevents it from being assignable to any type or named
type other than the untyped constant's default type.
Note that the added logic does not take into account the untyped
constant's value, so you will still get some false positive
completions (e.g. suggesting an untyped negative integer constant when
only a uint would do). Unfortunately go/types doesn't provide a way of
answering the question "is this *types.Const assignable to this
types.Type" since types.AssignableTo only considers a constant's type,
not its value.

Deep completion refers to searching through an object's fields and
methods for more completion candidates. For example:
func wantsInt(int) { }
var s struct { i int }
wantsInt(<>)
Will now give a candidate for "s.i" since its type matches the
expected type.
We limit to three deep completion results. In some cases there are
many useless deep completion matches. Showing too many options defeats
the purpose of "smart" completions. We also lower a completion item's
score according to its depth so that we favor shallower options. For
now we do not continue searching past function calls to limit our
search scope. In other words, we are not able to suggest results with
any chained fields/methods after the first method call.
Deep completions are behind the "useDeepCompletions" LSP config flag
for now.

func foo() int { return 0 }

f = <foo> // now completes to "foo" instead of "foo()"
Also, *types.Var function values were never getting expanded to calls.
I fixed the completion formatting to know that both *types.Func

When checking if a completion candidate matches the expected type at
the cursor position, we now use types.AssignableTo instead of
types.Identical. This properly handles cases like using a concrete
type to satisfy an interface type.
Calling AssignableTo triggered some crashes related to the fake
"resolved" types we create. Their underlying type was nil, which is
not allowed. We now set their underlying type to the invalid type.
I've also rearranged things so expected type information lives in a
dedicated typeInference struct. For now there is no new information added,
but in subsequent commits there will be more metadata about the
expected type.

Previously when you added a new file to an existing package, the new
file would get stuck with the "no package for file" error until you
saved the file and then made changed a different file in the
package. There were two changes required to fix the errors:
First, we need to invalidate the package cache when a new file is
added to a package so that the package will actually re-parse and
re-type check. We now notice if file names changed when updating a
package's metadata and invalidate the package cache accordingly.
Second, when dealing with overlay (unsaved) files, we need to map
the *goFile to the package even if we fail to parse the
file (e.g. the new file fails to parse when it is empty). If we don't
map it to the package, the package won't get refreshed as the file is
changed.

If the context is canceled (or times out) during parsing, we were
previously caching the package with no *ast.Files. Any further LSP
queries against that package would fail because the package is already
loaded, but none of the files are mapped to the package. Fix by
propagating non-parse errors as "fatal" errors in
parseFiles. typeCheck will propagate these errors and not cache the
package.
I also fixed the package cache to not cache errors loading
packages. If you get an error like "context canceled" then none of the
package's files are mapped to the package. This prevents the package
from ever getting unmapped when its files are updated. I also added a
retry mechanism where if the current request is not canceled but the
package failed to load due to a previous request being canceled, this
request can try loading the package again.

Completions like "foo.Bar(baz.<>)" were replacing one too many
characters resulting in "foo.Bar(baz.Qux()". This is because the go
parser adds a phantom "_" identifier when parsing "foo.". We thought
the "_" was really there, so we were issuing text edits to replace
it. Fix by ignoring "_" selectors when the cursor is positioned to
their left.

The insertion range for completion items was not right. The range's
end was 1 before the start. Fix by taking into account the length of
the prefix when generating the range start and end.
Now instead of a "prefix", we track the completion's
"surrounding". This is basically the start and end of the abutting
identifier along with the cursor position. When we insert the
completion text, we overwrite the entire identifier, not just the
prefix. This fixes postfix completion like completing "foo.<>Bar" to
"foo.BarBaz".

Fix the following issues:
- We were trying to complete struct literal field names for
selector expressions (e.g. "Foo{a.B<>}"). Now we only complete field
names in this case if the expression is an *ast.Ident.
- We weren't including lexical completions in cases where you might be
completing a field name or a variable name (e.g. "Foo{A<>}").
I refactored composite literal logic to live mostly in one place. Now
enclosingCompositeLiteral computes all the bits of information related
to composite literals. The expected type, completion, and snippet code
make use of those precalculated facts instead of redoing the work.

Now when you accept a struct literal field name completion, you will
get a snippet that includes the colon, a tab stop, and a comma if
the literal is multi-line. If you have "gopls.usePlaceholders"
enabled, you will get a placeholder with the field's type as well.
I pushed snippet generation into the "source" package so ast and type
info is available. This allows for smarter, more context aware snippet
generation. For example, this let me fix an issue with the function
snippets where "foo<>()" was completing to "foo(<>)()". Now we don't
add the function call snippet if the position is already in a CallExpr.
I also added a new "Insert" field to CompletionItem to store the plain
object name. This way, we don't have to undo label decorations when
generating the insert text for the completion response. I also changed
"filterText" to use this "Insert" field since you don't want the
filter text to include the extra label decorations.

*snippet.Builder helps you construct lsp completion snippet strings.
It handles escaping for you, and it gives a convenient interface for
writing nested placeholders.
Note that the builder does not support snippet "variables" or
associated features. They add a lot of complexity and don't seem very
useful at this point (plus they aren't supported in many editors).

This change adds support for completion of incomplete selectors after a
defer or go statement. We modify the AST before type-checking it with a
fake *ast.CallExpr.

Completion suppression in comments wasn't working for comments in
switch case statements, select case statements, and decl statements.
Rather than adding those to the list of leaf ast.Node types to look
for, we now always check if the position is in a comment. This fix
broke some completion tests that were using re"$" since "$" matches
after the comment "//" characters.
We now also don't complete within any literal values. Previously we
only excluded string literals.

This change propagates more errors from analyses, instead of just saving
them in act.err, we actually return immediately. Ultimately, we'd want

When the value of a composite literal key/value pair was unparsable,
you were getting completions for the composite literal keys instead of
values. For example "struct { foo int }{foo: []<>" was completing to
the field name "foo". This was because the leaf ast.Node at the cursor
was the composite literal itself, and our go-back-one-character logic
was not happening because the preceding character's node
was *ast.BadExpr, not *ast.Ident. Fix by always generating the ast
path for the character before the cursor's position. I couldn't find
any cases where this broke completion.
I also added expected type detection for the following composite
literal cases:
- array/slice literals
- struct literals (both implicit and explicit field names)
- map keys and values

When jumping to definition of an embedded struct pointer, be sure to
unwrap the pointer type so you properly jump to the pointee type.
Also, fix jumping to definition of an embedded struct inside an
anonymous struct inside a struct. The embedded struct detection was
continuing too far and thinking it wasn't an embedded struct when it
saw the anonymous struct.
