* update staticcheck
Don't fork staticcheck: use the upstream version.
Remove unneeded SSA loading.
* Cache go/analysis facts
Don't load unneeded packages for go/analysis.
Repeated run of go/analysis linters now 10x faster
(2s vs 20s on this repo) than before.
Don't perform extra go env calls in go/packages.
Load only needed go env vars in golangci-lint.
Stay in sync by enabled analyzers in go vet: remove nilness and
atomicalign analyzers, add errorsas analyzer.
Don't build SSA for govet.
Standalone govet runs 25% faster than before. All runs can be 5-10% faster
than before.
Relates: #208
This false-positive is not present in the upstream stand-alone 'unused'
2019.1.1 program that golangci-lint uses.
pkg/lint.ContextLoader.filterPackages() did two things:
1. It removed synthetic "testmain" packages (packages with .Name=="main"
and .PkgPath ending with ".test")
2. It removed pruned subsumed copies of packages; if a package with files
"a.go" and "a_test.go", it results in packages.Load giving us two
packages:
- ID=".../a" GoFiles=[a.go]
- ID=".../a [.../a.test]" GoFiles=[a.go a_test.go]
The first package is subsumed in the second, and leaving it around
results in duplicated work, and confuses the 'deadcode' linter.
However, the 'unused' linter relies on both the ".../a" and
".../a [.../a.test]" packages being present. Pruning them causes it to
panic in some situations, which lead to this workaround:
af6baa5dc1
While that workaround got it to not panic, it causes incorrect results.
So, split filterPackages() in to two functions: filterTestMainPackages()
and filterDuplicatePackages(). The linter.Context.Packages list only
gets filterTestMainPackages() called on it, while linter.Context.Program
and linter.Context.SSAProgram get both filters applied.
With the source of the panic fixed, roll back a few now-unnecessary
commits in go-tools.
Significantly improve CPU and memory usage when not using SSA-powered linters.
Improve readability of go/packages errors.
Improve debugging capabilities and write doc about debugging.
This update should fix go get issues because of deps.

Preprocessed files like .qtpl.go quicktemplate Go files can have
//line directives. They map to a source .qtpl file.
This commit fixes linting of such files:
1. don't fail on AST cache loading
2. output Go filename not .qtpl or similar
Also, here we update golint to the upstream version.
Relates: #316, #466, #467, #468
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)'"
Fixes#500
