This brings in the upstream fix
1aadbdfdbb. (Upstream
issue is https://github.com/golang/go/issues/31163).
To create this commit, I did:
vgo get golang.org/x/tools
make update_deps
cd cmd/golangci-lint
go install -ldflags "-X 'main.version=$(git describe --tags)' -X 'main.commit=$(git rev-parse --short HEAD)' -X 'main.date=$(date)'"

This updates the unparam linter to the current version that has fewer
false positives. The go.{mod,sum} files and the vendor folder are
updated as follows:
export GO111MODULE=on
go get -u mvdan.cc/unparam
go mod tidy
go mod vendor
The unparam callgraph algorithm is no longer selectable. Ref:
https://github.com/mvdan/unparam/commit/e6a6d1c5
This is the reason for removing the c.CallgraphAlgorithm(us.Algo) line
from pkg/golinters/unparam.go.
Also do following improvements:
- show proper sublinter name for megacheck sublinters
- refactor and make more simple and robust megacheck
merging/optimizing
- improve handling of unknown linter names in //nolint directives
- minimize diff of our megacheck version from the upstream,
https://github.com/golang/go/issues/29612 blocks usage of the upstream
version
- support the new `stylecheck` linter
- improve tests coverage for megacheck and nolint related cases
- update and use upstream versions of unparam and interfacer instead of forked
ones
- don't use golangci/tools repo anymore
- fix newly found issues after updating linters
Also should be noted that megacheck works much faster and consumes less
memory in the newest release, therefore golangci-lint works noticeably
faster and consumes less memory for large repos.

The new version of goimports works 100x faster
with go modules. Also it has some new features:

Use go/packages instead of x/tools/loader: it allows to work
with go modules and speedups loading of packages with the help
of build cache.
A lot of linters became "fast": they are enabled by --fast now and
work in 1-2 seconds. Only unparam, interfacer and megacheck
are "slow" linters now.
Average project is analyzed 20-40% faster than before if all linters are
enabled! If we enable all linters except unparam, interfacer and
megacheck analysis is 10-20x faster!
A recent change was introduced in goimports improving how it sort and
format imports in https://go-review.googlesource.com/c/tools/+/116795
This commit updates the vendored version of the golang.org/x/tools
repository to include these changes.
1. Support unparam linter and fix found issues
2. Replace forked mvdan.cc/lint and mvdan.cc/interfacer with the
upstream ones
3. Minimize forked megacheck: move the most of it's code to this repo
4. Use golang.org/x/tools/go/ssa import path instead of custom fork
paths
5. In golang.org/x/tools/go/{ssa,callgraph} use changed code from
honnef.co/go/tools
6. Add megacheck.check-unexported option: it found some issues in
the repo, fixed them all
