decl.c (components_need_strict_alignment): New.

* gcc-interface/decl.c (components_need_strict_alignment): New.
(components_to_record): Do not pack the variants if one of the fields
needs strict alignment.  Likewise for the variant part as a whole.
Specify the position of the variants even if the size isn't specified,
but do not specify the size of the variant part in this case.
