gdbarch structure.
	* gdbarch.{c,h}: Regenerate.

	* value.c (struct value): Replace BITS_BIG_ENDIAN by
	gdbarch_bits_big_endian (comment).
	(unpack_field_as_long, modify_field): Likewise.
	* value.h: Likewise (comment).
	* valops.c (value_slice): Likewise.
	* valarith.c (value_subscript, value_bit_index): Likewise.
	* gdbtypes.h (field): Likewise (comment).
	* eval.c (evaluate_subexp_standard): Likewise.
	* dwarf2read.c (dwarf2_add_field): Likewise.
	* ada-lang.c (decode_packed_array, ada_value_primitive_packed_val)
	(move_bits, ada_value_assign, value_assign_to_component): Likewise.

	* defs.h (BITS_BIG_ENDIAN): Remove.



	* gdbint.texinfo (Target Conditionals): Replace the description of
	BITS_BIG_ENDIAN with a description of gdbarch_bits_big_endian.
