Add support for anonymous classes

Has not landed upstream yet, but syntax is unlikely to change.

Poison attribute initializations in parser

Those should error if they end up being used.

Fix "print" pretty-printing

Precedence was previously ignored.

Add support for "yield from"

Clarify attribute assignment code

* Don't assign to attribute stack on reduce - why was that there
in the first place?
* Assign attributes to the position in the stack where the first
token of the production is, instead of one position earlier.
* Add a comment to clarify why we also assign attributes on read,
instead of just on shift.

Build node attributes inside semantic action methods

Minor performance improvement for parsing, also allows to access
attributes with higher granulity in the parser, though this is not
currently done.

* #n can now be used to access the stack position of a token. $n
is the same as $this->semStack[#n]. (Post-translate $n will
actually be the stack position.)
* $attributeStack is now $this->startAttributeStack and
$endAttributes is now $this->endAttributes.
* Attributes for a node are now computed inside the individual
reduction methods, instead of being passed as a parameter.
Accessible through the attributes() macro.

Version bump

Regenerate parser

Also drop the error() parser macro.

Merge primary error recovery code

The grammar does not yet actually implement error recovery.

Make column info 1-based

Add column info for non-syntax errors where relatively precise

Should it also be added if only rough information is available? E.g.
spanning an entire class?

Test parser position information (syntax errors)

Make Error column info attribute based

added column-numbers to syntax errors

Simplify code

The new class couldn't already exist at that point - if it did, the
old name would have been aliased already and the autoloader wouldn't
trigger.

Fix PHP 7 alias registration

This fixes the case where the old name is used before the new one
is ever used, e.g. when manually constructing nodes, as opposed to
parsing them.

Fix PHP 7 alias registration

This fixes the case where the old name is used before the new one
is ever used, e.g. when manually constructing nodes, as opposed to
parsing them.

The previous approach would try to register the alias from OLD to
NEW. This would trigger autoloading on NEW and afterwards it would
register the alias from OLD to NEW. Afterwards the alias registration
which originally triggered the autoload would run, thus redeclaring
the class.

TL;DR aliases suck, closes #192.

Release PHP-Parser 1.2.2

Don't set unserialize_callback_func in Autoloader::register() as it has side effects even when the library is not used

Add missing type hints

Resolve param type hints earlier

For convenience of concurrent visitors that want to perform
enterNode actions based on Stmt\Function_ etc.

Fixes #188.

Release PHP-Parser 1.2.1

Fix registering of PHP 7 aliases

The previous approach was causing issues, because "instanceof"
does not invoke the autoloader.

Strict type compliance

Were this library to be fully annotated with scalar types and
return types where possible and were strict types to be enabled
for all files, the test suite wou
