Keeping the distinction in the parser doesn't really give us any
benefit and only makes changing the grammar harder.

zend_ast_create determined child count automatically

Remove zend_ast_create_unary etc

Add zend_ast_list* variant to parser stack element

Minor cleanups in AST code

Use separate node type for lists

This saves storing the children count for normal ast nodes.

Store lineno for zval ast nodes more efficiently

Create namespace_name via AST

zend_do_return -> zend_emit_final_return

Make lexer return AST nodes

Add functions for create str/long ast directly

Fix leaks

Must find a good way to handle constant expressions...

Implement declare()

__halt_compiler() without haling compiler

Partial NS port (semicolon, no errors)

Port constant declaration

Port use statement

Partial port of class declarations

Prepare zend_ast_decl for reuse with classes

Port trait uses

Port class const decl

Port property declarations

Port methods

The duplicated magic method checks are ugly
