re PR c++/67354 (internal compiler error: in add_to_same_comdat_group, at symtab.c:421)
PR c++/67354
* cp-tree.h (defer_mangling_aliases): Declare.
(generate_mangling_aliases): New prototype.
* decl2.c (defer_mangling_aliases): New variable.
(note_mangling_alias): Use !defer_mangling_aliases
instead of at_eof.
(generate_mangling_aliases): No longer static. Clear
defer_mangling_aliases.
* optimize.c (maybe_thunk_body): Defer emitting mangling aliases
if !defer_mangling_aliases until the fns are put into the same
comdat group.
* g++.dg/abi/mangle67.C: New test.
