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!
