TARGET, BITSIZE, BITPOS, MODE, EXP are as for store_field.
TYPE is the type of the CONSTRUCTOR, not the element type.

ALIAS_SET is the alias set to use for any stores.
This provides a recursive shortcut back to store_constructor when it isn't
necessary to go through store_field. This is so that we can pass through
