re PR c++/79896 (ICE in gimplify_expr, at gimplify.c:11950 on non-int128 target)
PR c++/79896
* decl.c (finish_enum_value_list): If value is error_mark_node,
don't copy it and change its type.
* init.c (constant_value_1): Return error_mark_node if DECL_INITIAL
of CONST_DECL is error_mark_node.
* g++.dg/ext/int128-5.C: New test.
