Robert Findley 707beb0c63 internal/lsp/source: descend into fields and field lists in qualifyExpr
We do a lot of gymnastics to format var types, working around the lack
of alias tracking in go/types. As part of this, we clone and qualify
expressions. In this case, we were not qualifying identifiers that were
contained within fields or field lists.

Fix this by updating our expression traversal to include *ast.Field and
*ast.FieldList.

Fixes golang/go#50539

Heschi Kreinick aeb8e36929 internal/lsp: remove multi-module support in tests
Mostly a rollback of CL 217541. No changes in the actual tests.

Rohan Challa 2529d2857a internal/lsp/tests: standardize testdata folder format
This change standardizes the folder structure for testdata that are used for testing the lsp. In particular, it uses the following format:
- dir
  - primarymod
    - .go files
    - packages
    - go.mod (optional)
  - modules
    - repoa
      - mod1
        - .go files
        -  packages
        - go.mod (optional)

As we can see, any folder inside of testdata should be of this format, where the primary test files with the markers are all located inside the primarymod folder. The modules folder is used to hold any potential dependencies that are used for testing.

A consequence of this change is that we can have one directory separated by folders, where each folder is it's own module, this allows us to use internal/lsp/tests with go.mod files. Now, tests.Load() will return an array of Data objects, where each object corresponds to one of the directories structured above.

Updates golang/go#36091

Muir Manders 49797d04a8 internal/lsp/source: improve completion in type assertions
In cases like:

var foo *someType = bar.(some<>)

We will now complete "some" to "*someType". This involved two changes:

1. Properly detect expected type as *someType in above example. To do
   this I just removed *ast.TypeAssertExpr from
   breaksExpectedTypeInference() so we continue searching up the AST for
   the expected type.

2. If the given type name T doesn't match, also try *T. If *T does
   match, we mark the candidate as "makePointer=true" so we know to
   prepend the "*" when formatting the candidate.

Muir Manders e5f21acdc3 internal/lsp: handle more expected type cases
Calculate expected type in the following cases:

- switch case statements
- index expressions (e.g. []int{}[<>] or map[string]int{}[<>])
- slice expressions (e.g. []int{}[1:<>])
- channel send statements
- channel receive expression

We now also prefer type names in type switch clauses and type asserts.

Muir Manders 775b7fe395 internal/lsp: improve expected type determination
Improve expected type determination for the following cases:

- search back further through ast path to handle cases where the
  position's node is more than two nodes from the ancestor node with
  type information
- generate expected type for return statements
- wrap and unwrap pointerness from expected type when position is
  preceded by "*" (dereference) or "&" (reference) operators,
  respectively
- fix some false positive expected types when completing the "Fun"
  (left) side of a CallExpr
