Print all build errors in a readable way

[torkelrogstad]

Is your feature request related to a problem? Please describe.
When developing, my build is most of the time broken. I often want to identify all non-compiling packages. I can easily do this with go build for my main sources, but this does not work for test sources. I want an easy to use solution to find all my non-compiling tests.

Describe the solution you'd like
If I run golangci-lint run in a directory with several packages where tests can't compile, I want them to be printed to the console in the same way that linter errors are printed.

The functionality is already there: build errors are printed, but only the first error is printed and in a non-easy-to-use format. An example:

I have a file foo_test.go

package foo

import (
	"fmt"
	"testing"
)

func TestFoo(t *testing.T) {
	fmt.Prin()
}

If I now run golangci-lint run, I get this output:

WARN [runner] Can't run linter goanalysis_metalinter: S1021: failed prerequisites: [([email protected]/torkelrogstad/build-tests/foo [github.com/torkelrogstad/build-tests/foo.test], [email protected]/torkelrogstad/build-tests/foo [github.com/torkelrogstad/build-tests/foo.test]): analysis skipped: errors in package: [/Users/torkel/dev/build-tests/foo/foo_test.go:9:6: Prin not declared by package fmt]] 
WARN [runner] Can't run linter unused: buildir: analysis skipped: errors in package: [/Users/torkel/dev/build-tests/foo/foo_test.go:9:6: Prin not declared by package fmt] 
ERRO Running error: buildir: analysis skipped: errors in package: [/Users/torkel/dev/build-tests/foo/foo_test.go:9:6: Prin not declared by package fmt] 

It would be great to get this in the same format as linter errors.

I have this same exact request. Currently, the errors are unbelievably unreadable (I have a lot on a rather large code base I'm not trying to integrate golangci-lint with). I know it's possible to limit the errors, but still this would be really nice

Seems to be duplicate of #1043.
