internal/lsp: improve composite literal completion
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
Fixes golang/go#29153

This subrepository holds the source for various packages and tools that support the Go programming language.
Some of the tools, godoc and vet for example, are included in binary Go distributions.
Others, including the Go guru and the test coverage tool, can be fetched with go get.
Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.
The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.
The main issue tracker for the tools repository is located at https://github.com/golang/go/issues. Prefix your issue with “x/tools/(your subdir):” in the subject line, so it is easy to find.
