gopls/internal/regtest: add an option to nest the workdir

Add a regtest run option NestWorkdir, which causes the working directory
to be nested in the editor workspace, and use it in some modfile tests
to exercise the new workspace logic.

For now we only run the nested tests while using experimental workspace
modules. In a later CL, the 'legacy' mode will be updated to find a
solitary nested module, at which point we should be able to run nested
in all modes.

Fixes golang/go#42111

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.
