[C++PATCH] Lambda names are anonymous
https://gcc.gnu.org/ml/gcc-patches/2019-05/msg02126.html
* cp-tree.h (IDENTIFIER_LAMBDA_P): New.
(TYPE_ANON_P): New.
(LAMBDA_TYPE_P, TYPE_UNNAMED_P): Likewise.
(LAMBDANAME_PREFIX, LAMBDANAME_FORMAT): Delete.
(make_lambda_name): Don't declare.
* error.c (dump_aggr_type): Check for lambdas before other
anonymous names.
* lambda.c (begin_lambda_type): Use make_anon_name.
* cp-lang.c (cxx_dwarf_name): Lambda names smell anonymous.
* mangle.c (write_local_name): Likewise.
* name-lookup.c (lambda_cnt, make_lambda_name): Delete.
