Keeping the distinction in the parser doesn't really give us any

Introduce optional_expr

Remove parenthesis_expr

This was necessary previously to handle yields, now it only clutters
up the grammar.

Simplify `argument` production

Move =&new deprecation message into compiler

Handle remaining magic constants in parser as well

As far as I can see the !filename case cannot occur, so I dropped
it.

Add backup_doc_comment production

Bison can't detect the type of a mid-rule action, even if it accesses
$<str>$, so need to create a separate rule for this.

eval() with parse error uses clean shutdown now

Add type annotations to parser

As the encoding declaration influences lexing it needs to be

Add zend_ prefix for emit_op(_tmp)

zend_ast_create determined child count automatically

Remove zend_ast_create_unary etc

Cleanup dead/duplicate code

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.
