0ea134a507 Add PHP 8 parser with correct concatenation precedence 
The PHP 7 and PHP 8 parsers use the same grammar file and only
differ in token precedence.

b0469d127e Rename Expr\ClosureUse -> ClosureUse 
This is not a real expression, treat it similarly to Node\Arg
or Node\Param.

The old name is retained as an alias for compatibility.

08501991d4 Don't make VariadicPlaceholder an expression

13549aa794 Add support for first-class callables 
I'm somewhat unsure about the AST structure here.
VariadicPlaceholder is not a general expression. Maybe Arg->expr
should be Expr|VariadicPlaceholder? Or possibly the call arguments
should be an array of Arg|VariadicPlaceholder?

Add support for new PHP 8.1 modifiers (#796) 
Implement support for readonly properties (https://wiki.php.net/rfc/readonly_properties_v2) and
final class contstants (https://wiki.php.net/rfc/final_class_const).

c758510a37 Add support for PHP 8.1 
With the introduction of intersection types, PHP now lexes the
token '&' either as T_AMPERSAND_(NOT_)FOLLOWED_BY_VAR_OR_VARARG.
This completely breaks parsing of any code containing '&'.

Fix this by canonicalizing to the new token format (unconditionally,
independent of emulation) and adjusting the parser to use the two
new tokens.

This doesn't add actual support for intersection types yet.

[PHP 8.0] Add attributes support (#661) 
Adds support for PHP 8 attributes, represented using `AttrGroup` nodes
containing `Attribute` nodes. The `attrGroup` subnode is added to all
nodes that can have attributes.

This is still missing FPPP support.

f66a32e2df Emulate PHP 8 attribute syntax 
Perform emulation by replacing #[ with %[, then patching % back
to # and coalescing #[ into T_ATTRIBUTE if it is a freestanding
token.

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.
