PhpdocTypesFixer - support iterable type

[GrahamCampbell]

PHP 7.1 will have the iterable type. We should treat it like the other types we normalize.

• Iterable pseudo-type php/php-src#1941

Nice !

Could you please add small integration test for 7.1 (like this: https://github.com/FriendsOfPHP/PHP-CS-Fixer/blob/1.12/Symfony/CS/Tests/Fixtures/Integration/misc/PHP7.test) ?

I'm not saying to add all 7.1 (which of course would be nice), but at least iterable

Could you please add small integration test for 7.1

Why PHP 7.1. This phpdoc type can be used on any version, the same way string is used on PHP 5 even though it can't be type hinted until 7.0, and mixed isn't even a real type on any version.

[keradus]

iterable is not only for typedoc.
add function foo(iterable $bar) {} in integration test like we did for 7.0 syntax changes.

[GrahamCampbell]

This fixer change has nothing to do with actual typehints though, so in the interest of keeping this atomic, I shouldn't make an unrelated change.

[keradus]

then this PR would make false sense of feeling we support the iterable, even if we would support it only in doctype. big -1 for that

Thank you @GrahamCampbell.
