11bbd741f5 internal/memoize: changes to only one handle per key
This is to remove the confusion around having only handles that have had Get
called pin the value into memory.
Instead now there is a single handle per key, and it is the handle that is
weakly held not the value.

5999de1043 internal/lsp: tighten up completion budget check
Tweak a couple things to improve how we reduce our search scope based
on remaining time budget:

- Check our budget on the first candidate rather than waiting for the
  1000th candidate. If type checking is slow you can be out of budget
  before you even begin.
- Reduce our budget check interval from 1000 candidates to 100
  candidates. This just helps us adjust our search scope faster.

The first tweak required me to raise the completion budget for tests
because 100ms is not always enough. I moved the budget into the
completion options so that tests can raise it.

Revert my previous change to include fuzzy matches with a score of

5edc6aefed internal/lsp: reduce usage of column mapper
A mapper is always uniquely tied to a file at a specific version, so
just build it when we get a new *ast.File. We build the mapper using the
*token.File associated with the particular *ast.File, which is why there
is one per ParseGoHandle instead of FileHandle.

b31ee645dd internal/lsp: avoid unnecessary type checking
Previously we would type check all package handles as we fetched them.
This meant if you only cared about a file's primary package you would
still have to wait for all its packages to be type checked. For
example, when completing in foo.go, you would wait for [foo.go] and
[foo.go, foo_test.go] to be checked (the latter being the test
variant).

Now we don't type check packages as we put together the package
handles.

3720d1ec36 go/packages: suppress go list -e error when directory outside modules
If an absolute directory path being listed is outside any modules,
go list -e returns a non-zero exit status and non-empty stderr, but
should suppress the error. This was causing a weird bug when golang.org/cl/186337
was submitted because that changed the conditions when -export was passed,
which in turn affected how we suppressed the go list -e error (because
-export causes a compile it overtriggers errors, so we explicitly
suppress errors in that case). The way the error was being suppressed,
no error was generated, and no fake package was generated (which go list
is supposed to do), so the contains query fallback code wasn't run.

Before separating Load* into Need* we could use LoadSyntax
to get types information by loading inital packages
from source code and loading it's direct dependencies from export data.
It was broken when separation was introduced and before this commit
everything was loading from source code what resulted into slow
loading times. This commit fixes it.

Also, do backwards-incompatible fix of definition of deprecated
LoadImports and LoadAllSyntax.

Improve an internal error message
"internal error: nil Pkg importing x from y": replace it with
"internal error: package x without types was imported from y".

Remove packages.NeedDeps request for loading in tests
TestLoadTypesBits and TestContainsOverlayXTest.

7f5965fd77 internal/imports: fix scanning GOROOT in module mode
Go 1.13 introduced a module in GOROOT/src. That triggered goimports to
think that it was an invalid module, usable only as a replace target,
because its declared module path "std" didn't match its apparent path
"src". The stdlib is always in scope, so skip the needs-replace check
for GOROOT.

Fixes golang/go#34199

3e6e7c4239 internal/lsp: add ID to the package cache key
Our original caching plan was to use only the file ParseGoHandles as
cache keys to define a given package. However, because of package test
variants, we cannot rely on files alone. A package may have the exact
same set of files, but be a test variant. Add the ID to the key to avoid
clobbering entries in the cache.

Also, remove the unused metadata ID cache.

d0542c01b0 internal/imports: add all interfaces in mkstdlib
In api/*.txt, interface declarations are represented with lines like:
  pkg container/heap, type Interface interface { Len, Less, Pop, Push, Swap }
or, when they have no exported methods:
  pkg go/ast, type Expr interface, unexported methods

The latter form confuses mkstdlib into thinking that it's a method
because of the extra comma, and then it skips the interface entirely.
Running this program is a matter of seconds once per release, so rather
than trying to fix the optimization, just remove it. The parsing logic
doesn't care about the extra lines.

And the corresponding change to the copy in lsp/testdata/unimported.

5e3480f0e0 internal/lsp: start handling watched file deletes
Now when a file is deleted we force the file's packages to refresh
go/packages metadata, and kick off diagnostics.

I made a couple other changes to watched file handling:
- Kick off diagnostics in a goroutine to match how DidChange works.
  This will allow us to work through big sets of file changes faster,
  and will save duplicated work once type checking can be canceled.
- Don't assume a watched file is only part of one view.

Two interesting cases we don't handle yet:
- If the deleted file was the only file in the package, we don't
  currently update diagnostics for dependent packages. This requires
  rejiggering how diagnostics are invoked a bit.
- If the deleted file is still open in the editor and then later
  closed, we don't trigger metadata/diagnostics refresh on DidClose.

Updates golang/go#31553

3cd124fa3e internal/lsp: fix completion for nested *ast.BadStmt
Now when trying to fix *ast.BadStmt, we parse the manually extracted
expression using parser.ParseFile instead of parser.ParseExpr.
ParseFile will yield *ast.BadStmt nodes for any bad statements nested
in our first bad statement, allowing us to fix them recursively.

To turn our expression into a "valid" file we can pass to
parser.ParseFile, I wrapped it thusly:

package fake

func _() {
  <our expression>
}

238129aa63 internal/lsp: derive ASTs from type information
In the case of documentation items for completion items, we should make
sure to use the ASTs and type information for the originating package.
To do this while avoiding race conditions, we have to do this by
breadth-first searching the top-level package and its dependencies.

dd2b5c81c5 internal/lsp: simplify snippet config/generation
I moved the "usePlaceholders" config field on to CompletionOptions.
This way the completion code generates a single snippet with a little
conditional logic based on the "WantPlaceholders" option instead of
juggling the generation of two almost identical "plain" and
"placeholder" snippets at the same time. It also reduces the work done
generating completion candidates a little.

I also made a minor tweak to the snippet builder where empty
placeholders are now always represented as e.g "${1:}" instead of
"${1}" or "${1:}", depending on if you passed a callback to
WritePlaceholder() or not.

Add a new @completePartial note that does not require you to specify
the full list of completions. This gets rid of a lot of noise when you
just want to test the relative order of some completion candidates but
don't care about all the other candidates in scope.

I changed one existing test to use @completePartial as an example.
