Generate proxy VAR_DECLs for better lambda debug info.
* cp-tree.h (FUNCTION_NEEDS_BODY_BLOCK): Add lambda operator().
(LAMBDA_EXPR_PENDING_PROXIES): New.
(struct tree_lambda_expr): Add pending_proxies.
* name-lookup.c (pushdecl_maybe_friend_1): Handle capture shadowing.
(qualify_lookup): Use is_lambda_ignored_entity.
* parser.c (cp_parser_lambda_expression): Don't adjust field names.
Call insert_pending_capture_proxies.
(cp_parser_lambda_introducer): Use this_identifier.
(cp_parser_lambda_declarator_opt): Call the object parameter
of the op() __closure instead of this.
(cp_parser_lambda_body): Call build_capture_proxy.
* semantics.c (build_capture_proxy, is_lambda_ignored_entity): New.
(insert_pending_capture_proxies, insert_capture_proxy): New.
(is_normal_capture_proxy, is_capture_proxy): New.
(add_capture): Add __ to field names here, return capture proxy.
(add_default_capture): Use this_identifier, adjust to expect
add_capture to return a capture proxy.
(outer_lambda_capture_p, thisify_lambda_field): Remove.
(finish_id_expression, lambda_expr_this_capture): Adjust.
(build_lambda_expr): Initialize LAMBDA_EXPR_PENDING_PROXIES.
* pt.c (tsubst_copy_and_build): Check that LAMBDA_EXPR_PENDING_PROXIES
is null.
