Support GTY((cache)) on hash_map.
gcc/
* hash-traits.h (ggc_remove): Add ggc_maybe_mx member function.
(ggc_cache_remove): Override it instead of ggc_mx.
* hash-table.h (gt_ggc_mx): Call it instead of ggc_mx.
(gt_cleare_cache): Call ggc_mx instead of gt_ggc_mx.
* hash-map-traits.h (simple_hashmap_traits): Add maybe_mx member.
(simple_cache_map_traits): Override maybe_mx.
* hash-map.h (hash_entry): Add ggc_maybe_mx and keep_cache_entry.
(hash_map): Friend gt_cleare_cache.
(gt_cleare_cache): New.
* tree.h (tree_cache_traits): New hash_map traits class.
(tree_cache_map): New typedef.
gcc/cp/
