[PATCH v5 06/15] vla: update type from newly created value

[Sanimir Agovic <sanimir.agovic@intel.com>]

Constructing a value based on a type and address might change the type
of the newly constructed value. Thus re-fetch type via value_type to ensure
we have the correct type at hand.

            Keven Boell  <keven.boell@intel.com>

	* ada-lang.c (ada_value_primitive_packed_val): Re-fetch type from value.
	(ada_template_to_fixed_record_type_1): Likewise.
	(ada_to_fixed_type_1): Likewise.
	* cp-valprint.c (cp_print_value_fields_rtti): Likewise.
	(cp_print_value): Likewise.
	* d-valprint.c (dynamic_array_type): Likewise.
	* jv-valprint.c (java_value_print): Likewise.
	* valops.c (value_ind): Likewise.
	* value.c (coerce_ref): Likewise.
