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...

The parser will now always generate Identifier nodes (for

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.

Don't require useNopStatements=false for format preservation

Instead assign attributes on Nop nodes and in the pretty printer
specially handle end<start offsets. It's a somewhat weird case,
but not wrong per se given the meaning the offsets have.

Add useIdentifierNodes mode to parser

In this mode non-namespaced names that are currently represented
using strings will be represented using Identifier nodes instead.
Identifier nodes have a string $name subnode and coerce to string.

This allows preserving attributes and in particular location
information on identifiers.

Improve LNumber/DNumber pretty printing

* Support INF/-INF/NAN in namespaces

Add string kinds and doc string labels

Add string kinds and doc string labels

Scalar\String_ and Scalar\Encapsed now have an additional "kind"
attribute, which may be one of:

* String_::KIND_SINGLE_QUOTED
* String_::KIND_DOUBLE_QUOTED
* String_::KIND_NOWDOC
* String_::KIND_HEREDOC

Additionally, if the string kind is one of the latter two, an
attribute "docLabel" is provided, which contains the doc string
label (STR in <<<STR) that was originally used.

The pretty printer will try to take the original kind of the string,
as well as the used doc string label into account.
