b241a121a3 Fix trait alias to semi-reserved name parsing 
This was missing the explicit construction of an Identifier node.

5054a68bfb Reset origTokens in resetState() 
In case one pretty printer is used in both preserving and
non-preserving mode.

5900d78cc9 FPPP: Support anonymous classes (#432) 
This is a huge hack... We temporarily create a new node with the
correct structure and use that for printing.

I think it would be better to always use a separate node type for
NewAnonClass, rather than using a combination of New and Class,
but this would require some larger changes, as this node type would
have to be both Expr and ClassLike, which is not possible right now,
as the latter is a class rather than an interface...

776275361a FPPP: Support modifier changes (#428) 
I decided against introducing a node type for this. In the end it
would require special handling anyway.

3da189769c Distinguish between implicit/explicit alias 
The UseUse::$alias node can now be null if an alias is not
explicitly given. As such "use Foo\Bar" and "use Foo\Bar as Bar"
are now represented differently.

The UseUse->getAlias() method replicates the previous semantics,
by returning "Bar" in both cases.

a6846e3b71 Always use Identifier nodes 
The parser will now always generate Identifier nodes (for
non-namespaced identifiers). This obsoletes the useIdentifierNodes
parser option.

Node constructors still accepts strings and will implicitly create
an Identifier wrapper. Identifier implement __toString(), so that
outside of strict-mode many things continue to work without changes.

8f623fb241 Use closures instead of methods for semantic actions 
The dispatch using $this->{'reduceRule' . $rule}() is very expensive
because it involves
 * One allocation when converting $rule to a string
 * Another allocation when concatenating the two strings
 * Lowercasing during the method call
 * Various uncached method checks, e.g. visibility.

Using an array of closures for semantic action dispatch is
significantly more efficient.

3bbf8d8f7a Use local var for $stackPos 
We're accessing $this->stackPos a lot, and property accesses are
much more expensive than local variable acesses. Its cheaper to
use a local var and pass it as an argument to semantic actions.
