* valops.c (value_fetch_lazy): Handle bitfields explicitly.
(value_assign): Remove unnecessary FIXME. Honor the container
type of bitfields if possible.
* value.c (struct value): Add parent field.
(value_parent): New function.
(value_free): Free the parent also.
(value_copy): Copy the parent also.
(value_primitive_field): Do not read the contents of a lazy
value to create a child bitfield value. Set bitpos and offset
according to the container type if possible.
(unpack_bits_as_long): Rename from unpack_field_as_long. Take
field_type, bitpos, and bitsize instead of type and fieldno.
(unpack_field_as_long): Use unpack_bits_as_long.
* value.h (value_parent, unpack_bits_as_long): New prototypes.
