alias.c (get_alias_set): Before checking TYPE_ALIAS_SET_KNOWN_P double check that type is main variant.
* alias.c (get_alias_set): Before checking TYPE_ALIAS_SET_KNOWN_P
double check that type is main variant.
* tree.c (build_variant_type_copy): Clear TYPE_ALIAS_SET when producing
variant.
(verify_type_variant): Verify that variants have no
TYPE_ALIAS_SET_KNOWN_P set
* tree-streamer-out.c (pack_ts_type_common_value_fields): Reorder
streaming so constant fields come first; stream TYPE_ALIAS_SET==0
only for main variants; stream TYPE_ALIAS_SET as a bit.
* tree-streamer-in.c (unpack_ts_type_common_value_fields): Update
accordingly.
