Don't lose embedded_offset in printing routines throughout.

	gdb/
	* valprint.h (val_print_array_elements): Change prototype.
	* valprint.c (val_print_array_elements): Add `embedded_offset'
	parameter, and adjust to pass it down to val_print, while passing
	`valaddr' or `address' unmodified.  Take embedded_offset into
	account when checking repetitions.
	* c-valprint.c (c_val_print): Pass embedded_offset to
	val_print_array_elements instead of adjusting `valaddr' and
	`address'.
	* m2-valprint.c (m2_print_array_contents, m2_val_print): Pass
	embedded_offset to val_print_array_elements instead of adjusting
	`valaddr'.
	* p-lang.h (pascal_object_print_value_fields): Adjust prototype.
	* p-valprint.c (pascal_val_print): Pass embedded_offset to
	val_print_array_elements and pascal_object_print_value_fields
	instead of adjusting `valaddr'.
	(pascal_object_print_value_fields): Add `offset' parameter, and
	adjust to use it.
	(pascal_object_print_value): Add `offset' parameter, and adjust to
	use it.
	(pascal_object_print_static_field): Use
	value_contents_for_printing/value_embedded_offset, rather than
	value_contents.
	* ada-valprint.c (val_print_packed_array_elements): Add `offset'
	parameter, and adjust to use it.  Use
	value_contents_for_printing/value_embedded_offset, rather than
	value_contents.
	(ada_val_print): Rename `valaddr0' parameter to `valaddr'.
	(ada_val_print_array): Add `offset' parameter, and adjust to use
	it.
	(ada_val_print_1): Rename `valaddr0' parameter to `valaddr', and
	`embedded_offset' to `offset'.  Don't re-adjust `valaddr'.
	Instead work with offsets.  Use
	value_contents_for_printing/value_embedded_offset, rather than
	value_contents.  Change `defer_val_int' local type to CORE_ADDR,
	and use value_from_pointer to extract a target pointer, rather
	than value_from_longest.
	(print_variant_part): Add `offset' parameter.  Replace
	`outer_valaddr' parameter by a new `outer_offset' parameter.
	Don't re-adjust `valaddr'.  Instead pass down adjusted offsets.
	(ada_value_print): Use
	value_contents_for_printing/value_embedded_offset, rather than
	value_contents.
	(print_record): Add `offset' parameter, and adjust to pass it
	down.
	(print_field_values): Add `offset' parameter.  Replace
	`outer_valaddr' parameter by a new `outer_offset' parameter.
	Don't re-adjust `valaddr'.  Instead pass down adjusted offsets.
	Use value_contents_for_printing/value_embedded_offset, rather than
	value_contents.
	* d-valprint.c (dynamic_array_type): Use
	value_contents_for_printing/value_embedded_offset, rather than
	value_contents.
	* jv-valprint.c (java_print_value_fields): Add `offset' parameter.
	Don't re-adjust `valaddr'.  Instead pass down adjusted offsets.
	(java_print_value_fields): Take `offset' into account.  Don't
	re-adjust `valaddr'.  Instead pass down adjusted offsets.
	(java_val_print): Take `embedded_offset' into account.  Pass it to
	java_print_value_fields.
	* f-valprint.c (f77_print_array_1): Add `embedded_offset'
	parameter.  Don't re-adjust `valaddr' or `address'.  Instead pass
	down adjusted offsets.
	(f77_print_array): Add `embedded_offset' parameter.  Pass it down.
	(f_val_print): Take `embedded_offset' into account.

	gdb/testsuite/
	* gdb.base/printcmds.c (some_struct): New struct and instance.
	* gdb.base/printcmds.exp (test_print_repeats_embedded_array): New
	procedure.
	<global scope>: Call it.
