Patch number 3 handled scalar assignments like:
scalar_some_type = some_type(...)

Patch number 4 handled array assignments like:
array_some_type = (/some_type :: .../)

This takes care of assignments like:
array_some_type = some_type(...)
i.e. scalar to array assignments.  As all the infrastructure has been installed
previously, this simply sets it up properly.

OK?

	* trans-array.c (gfc_add_loop_ss_code): Use RESTRICTED field.
	* trans-expr.c (gfc_trans_assignment): Set RESTRICTED field.
