568236a305 Allow expressions in list()
Similar to the previous commit: list() syntactically accepts any
expression and non-variables are compile-time errors. The special
case of ($a) ends up being legal by accident.

9dda080a9d Allow expressions in isset()
Partial fix for #653. PHP 7 allows expressions inside isset(), but
rejects non-variables in the compiler. A side-effect of this is that
isset(($x)) is allowed, though this is not intentional.

46cbd9393a Place Nop nodes more precisely
If the Nop is created to collect comments, place it directly after
the comment, instead of at the next non-whitespace character.

We definitely need to introduce a general "Type" abstraction in

60d025a914 Fix attributes for zero-length nop nodes
Previously zero-length nop nodes used the lookahead start attributes
and current end attributes. This choice ends up being somewhat weird,
because the end attributes will be the at the last non-whitespace,
non-comment token, which might be quite far back. More problematically,
we may not have encountered any non-discarded token if we're at the
start of the file, in which case we will have no end attributes to
assign.

Change things to use a canonical "zero-length" node representation,
where the end position (token & file) will be exactly one before the
start position.

Fixes #589.

5f73c4de80 Flexible doc: Validate end label indentation
Move doc string parsing logic from rebuildParsers.php and
String_::parseDocString() into ParserAbstract. This stuff is
going to get complicated now.

For now only implement the validation of the indentation on the
end label.

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.

df98b0417b Handle "extends static" etc more gracefully
Use class_name production and emit the same error as for
"extends self" and "extends parent". It's weird that "extends
static" gives a different result than those two.

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.
