Several places define hash traits for integers, using particular integer
values as "empty" and "deleted" markers.  This patch defines them in terms
of a single int_hash class.

I also needed to extend gengtype to accept "+" in template arguments.


gcc/
        * gengtype-parse.c (require_template_declaration): Allow '+' in
        template parameters.  Consolidate cases.
        * hash-traits.h (int_hash): New class.
        * alias.c (alias_set_hash): New structure.
        (alias_set_traits): Use it.
        * symbol-summary.h (function_summary::map_hash): New class.
        (function_summary::summary_hashmap_traits): Use it.
        * tree-inline.h (dependence_hash): New class.
        (dependence_hasher): Use it.
        * tree-ssa-reassoc.c (oecount_hasher): Use int_hash.
        * value-prof.c (profile_id_hash): New class.
        (profile_id_traits): Use it.

OK.
