0f582e1708 Add VarLikeIdentifier
For representing Identifiers that have an implicit leading $.

With this done, maybe go one step further?
 * Rename VarLikeIdentifier -> VarIdentifier / VarName
 * Use VarIdentifier / VarName also as an inner node in Variable.
   Not sure if this adds any real value.

a947e731c3 Add useConsistentVariableNodes mode
The parameter case is a bit weird, because the subnode is called
"name" here, rather than "var". Nothing we can do about that in
this version though.

The two parser options might be merged. I've kept it separate,
because I think this variable representation should become the
default (or even only representation) in the future, while I'm
less sure about the Identifier thing.

6bcc6c31dd 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.

caa5c0cc76 Graceful handling for "special" errors
Nearly all special errors are now handled gracefully, i.e. the
parser will be able to continue after encountering them. In some
cases the associated error range has been improved using the new
end attribute stack.

To achieve this the error handling code has been moved out of the
node constructors and into special methods in the parser.

17d1e738fa Don't use ~__EMU sequences in emulative lexer
These were necessary back in the day when we had to emulate some
complex functionality such as nowdoc strings. Now we can simply
directly translate certain token sequences.

The motivation for this change is to avoid preprocessing of the source
code, which would complicate offset-aware error handling inside the
lexer as offsets would no longer be correct.

977cbab8e7 Decrement errorState when recovering from -> error
It's likely that an error after -> will trigger another one due to
missing semicolon without shifting a single token. We prevent an

which will suppress the duplicate error message, but allow error
recovery.

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.

This should be enough for all cases, because: A double has 53 bits
of mantissa (including the implicit 1 bit), which is 53*ln(2)/ln(10)
= 15.95 decimal digits. However the leading decimal digit may encode
less than the usual 3.32 bits, which will push this over the edge to
requiring 17 decimal digits.

* Attributes for a node are now computed inside the individual
  reduction methods, instead of being passed as a parameter.

6aaa87f143 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.

a2d7e8977a Use real properties for storing subnodes
Instead of storing subnodes in a subNodes dictionary, they are
now stored as simple properties. This requires declarating the
properties, assigning them in the constructor, overriding
the getSubNodeNames() method and passing NULL to the first argument
of the NodeAbstract constructor.

[Deprecated: It's still possible to use the old mode of operation
for custom nodes by passing an array of subnodes to the constructor.]

The only behavior difference this should cause is that getSubNodeNames()
will always return the original subnode names and skip any additional
properties that were dynamically added. E.g. this means that the
"namespacedName" node added by the NameResolver visitor is not treated
as a subnode, but as a dynamic property instead.

This change improves performance and memory usage.
