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.

b9b45dd2bc Insert T_BAD_CHARACTER tokens for missing characters 
The token stream should cover all characters in the original code,
insert a dummy token for missing illegal characters. We should
really be doing this in token_get_all() as well.

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.

f42bbc2403 Avoid default action for error production 
error is not necessarily going to have a semantic value, make sure
that the default action $$=$1 is not used.

0ed9065b4c Flexible doc: Validate and strip indentation 
If indentation is invalid, we strip on a best-effort basis.

The error position information is not great, but I don't want to
introduce sub-token error positioning at this point in time.

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.

83766c8c0e Partial support for flexible heredoc/nowdoc 
This only implements the token emulation part, it does not yet
handle the indentation stripping.

Emulating this feature on old PHP versions is really tough and is
not going to work perfectly, but hopefully this implementation is
"good enough".
