internal/lsp/source: add some additional symbol downranking

Downrank symbols if they are:
 1. Unexported and outside of the workspace. Since one wouldn't jump to
    these symbols to e.g. view documentation, they are less relevant.
 2. Fields and interface methods. Usually one would jump to the type
    name, so having fields highly ranked can be noisy.

To facilitate this change and more generally clean up, symbolCollector
is refactored to pass around slices of *ast.Idents rather than build up
'.' separated names as it traverses nested nodes.

For golang/go#40548

Go Tools

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.

Download/Install

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.

JS/CSS Formatting

This repository uses prettier to format JS and CSS files.

The version of prettier used is 1.18.2.

It is encouraged that all JS and CSS code be run through this before submitting a change. However, it is not a strict requirement enforced by CI.

Report Issues / Send Patches

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.
