Support match expression v2 rfc (#161)

The naming is based on `switch` statements.
Note that even if statement blocks were supported after a future RFC
those would probably be considered block **expressions**,
hence the `expr` name for `AST_MATCH_ARM`.

* Regenerate ast_stub.php

Add AST_PROP_GROUP in version 70.

The type information is deliberately left out of versions < 70.

`children['type']` is a Node describing the type of the property group,
or null.

The property visibility modifier flags were moved to the AST_PROP_GROUP.

Remove unused AST kinds

Don't use Decl nodes in version 50

Support nullable types

Represent these using a new AST_NULLABLE_TYPE virtual node.

Make generate_ast_data independent of zend_ast.h

Depending on this file is a problem if we want to support multiple
versions of PHP.

Avoid premature macro resolution / Fix OSX build

AST_STR(true) and AST_STR(false) were resolved to AST_STR(1) and
AST_STR(0), so go back to using a str_ prefix everywhere.

Rename some child names

Change some node names

Use AST_VAR node for static var + catch var

For version 20. Previously this was a simple string with the
variable name.

Use string child names for non-list nodes

Implementation needs some polishing.
