internal/lsp: add parse errors as diagnostics even when parsing fails

When a package consists of files that only fail to parse, we fail to
associate parse errors with the package, and therefore return no
diagnostics. To address this, we need to associate the errors with the
package. This involves adding a *token.File to the parseGoData so that
error messages and positions can be properly extracted, even when there
is no associated AST.

Fixes golang/go#39763

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.
