c++: duplicate alias templates with decltype [PR 99425]
This failure was ultimately from incorrect handling of alias
templates, but required a specific set of occurrences to happen in the
specialization hash table. This cleans up the specialization
streaming to add alias instantiations at the same point as other
instantiations. I also removed some unneeded global variables dealing
with mapping of duplicate decl contexts.
PR c++/99425
gcc/cp/
* cp-tree.h (map_context_from, map_context_to): Delete.
(add_mergeable_specialization): Add is_alias parm.
* pt.c (add_mergeable_specialization): Add is_alias parm, add them.
* module.cc (map_context_from, map_context_to): Delete.
(trees_in::decl_value): Add specializations later, adjust call.
Drop useless alias lookup. Set duplicate fn parm context.
(check_mergeable_decl): Drop context mapping.
(trees_in::is_matching_decl): Likewise.
(trees_in::read_function_def): Drop parameter context adjustment
here.
