* decl.c (maybe_pad_type): Use TYPE_SIZE_UNIT of the input type for
TYPE_SIZE_UNIT of result type if SIZE is not specified.
(make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation
of a bitfield, which we know is useless and causes trouble because of
alignment implications.
* utils.c (create_var_decl): Set DECL_COMMON again on targets without
BSS sections.
(process_attributes): Clear DECL_COMMON again when a section attribute
is present.
(finish_record_type): Independently track if RECORD_TYPE has SIZE and/or

(create_field_decl): Special case ADDRESSABLE negative to mean
"no bitfield creation", to be used by make_aligning_type. Don't
restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
fields claimed addressable still have to be bitfields. Use
value_factor_p instead of a raw binop construction to check for the
position's alignment.
