4.x - refactor unused variable detection 
This turns unused variable detection into an explicit control-flow problem, where before we had a more simplistic mark-and-sweep algorithm

Test parallelization (#4045) 
* Run tests in random order

Being able to run tests in any order is a pre-requisite for being able
to run them in parallel.

* Reset type coverage between tests, fix affected tests

* Reset parser and lexer between test runs and on php version change

Previously lexer was reset, but parser kept the reference to the old
one, and reference to the parser was kept by StatementsProvider. This
resulted in order-dependent tests - if the parser was first initialized
with phpVersion set to 7.4 then arrow functions worked fine, but were
failing when the parser was initially constructed with settings for 7.3

This can be demonstrated on current master by upgrading to
nikic/php-parser:4.9 and running:

```
vendor/bin/phpunit --no-coverage --filter="inferredArgArrowFunction" tests/ClosureTest.php
```

Now all tests using PHP 7.4 features must set the PHP version
accordingly.

* Marked more tests using 7.4 syntax

* Reset newline-between-annotation flag between tests

* Resolve real paths before passing them to checkPaths

When checkPaths is called from psalm.php the paths are resolved, so we
just mimicking SUT behaviour here.

* Restore newline-between-annotations in DocCommentTest

* Tweak Appveyor caches

* Tweak TravisCI caches

* Tweak CircleCI caches

* Run tests in parallel

Use `vendor/bin/paratest` instead of `vendor/bin/phpunit`

* Use default paratest runner on Windows

WrapperRunner is not supported on Windows.

* TRAVIS_TAG could be empty

* Restore appveyor conditional caching

f15cc7dd5b Mark private properties unused when referenced only in constructor (#1962) 
* Mark private properties unused when referenced only in constructor

If a private property is used only in constructor then most likely
it's a dead code since there is no need to have the class property.
But such static properties can be accessed between the calls.

* Ignore the private property issue on alter

* Fix the related dead code psalm

* Add a missing condition into the test
