std packages are a special case of the internal package check.

This test assumes that syscall.ByteSliceFromString refers to internal/bytealg.

-- go.mod --
module testdata
go 1.12

-- a/a.go --
package a

import "syscall"

var _, _ = syscall.ByteSliceFromString("") //@ inline(re"ByteSliceFromString", re`inaccessible package "internal/bytealg"`)
