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
just to defeat literal completions. My tests were failing mysteriously
due to having snippets disabled, and it was hard to figure out why.

WorkspaceSymbols matches symbols across views using the given query,
according to the matcher Matcher.
The workspace symbol method is defined in the spec as follows:
> The workspace symbol request is sent from the client to the server to
> list project-wide symbols matching the query string.
It is unclear what "project-wide" means here, but given the parameters
of workspace/symbol do not include any workspace identifier, then it has
to be assumed that "project-wide" means "across all workspaces". Hence
why WorkspaceSymbols receives the views []View.
However, it then becomes unclear what it would mean to call
WorkspaceSymbols with a different configured Matcher per View.
Therefore we assume that Session level configuration will define the
Matcher to be used for the WorkspaceSymbols method.
