gcc/ChangeLog.gimple-classes:
* ipa-icf-gimple.c (func_checker::compare_bb): Add checked casts.
(func_checker::compare_gimple_assign): Strengthen params from
gimple to const gassign *.
* ipa-icf-gimple.h (func_checker::compare_gimple_assign):
Likewise.

* ipa-prop.c (stmt_may_be_vtbl_ptr_store): Replace
is_gimple_assign with dyn_cast, introducing local gassign *
"assign_stmt" and using it in place of "stmt" for typesafety.
