Implement late-specified return type using 'auto'.
* cp-tree.h (struct cp_declarator): Add late_return_type field to
function declarator.
* parser.c (cp_parser_late_return_type_opt): New fn.
(cp_parser_direct_declarator): Use it.
(make_call_declarator): Put it in the declarator.
* decl.c (grokdeclarator): Splice in late-specified return type.
* pt.c (splice_late_return_type): New fn.
