Out Of Memory failures for `staticcheck` on travis (GOGC=5, concurrency=1)

[katbyte]

After working fine for 6ish months we have had to disable static-check linter on the terraform azure provider as we were unable to get it to finish anymore in travis due to it running out of memory. We have set concurrency to 1 and GOGC=5.

Please include the following information:

1. Version of golangci-lint: golangci-lint --version (or git commit if you don't use binary distribution)
   travis does a GO111MODULE=off go get -u github.com/golangci/golangci-lint/cmd/golangci-lint each run

2. Config file: cat .golangci.yml

GOGC=5 (while true; do sleep 300; echo "(Hey travis! I'm still alive and linting)"; done) & PID=$$!; echo $$PID; \
	golangci-lint run ./... -v --no-config --concurrency 1 --deadline=30m10s --disable-all --enable=staticcheck; ES=$$?; kill -9 $$PID; exit $$ES

3. Go environment: go version && go env
   travis:

dist: xenial
sudo: required
services:
- docker
language: go
go:
- "1.13.x"

branches:
  only:
    - master

env:
  global:
    GOFLAGS=-mod=vendor

4. Verbose output of running: golangci-lint run -v

Hi!
Please, try the latest version from the master. I've reduced memory usage of staticcheck on your repo from 8GB to 2GB.

[jirfag]

let's continue in #337, there are too many similar issues about memory
