Fix PR 16722 by adding support for 8-byte vector constants.
* config/tc-arm.c (literal_pool): New field "alignment".
(find_or_make_literal_pool): Initialize "alignment" to 2.
(s_ltorg): Align the pool using value of "alignment"
(parse_big_immediate): New parameter "in_exp". Return
parsed expression if "in_exp" is not null.
(parse_address_main): Invoke "parse_big_immediate" for
constant parameter.
(add_to_lit_pool): Add one parameter 'nbytes'.
Split 8 byte entry into two 4 byte entry.
Add padding to align 8 byte entry to 8 byte boundary.
(encode_arm_cp_address): Generate literal pool entry if possible.
(move_or_literal_pool): Generate entry for vldr case.
(enum lit_type): New enum type.
(do_ldst): Use new enum type.
(do_ldstv4): Likewise.
(do_t_ldst): Likewise.
(neon_write_immbits): Support Thumb-2 mode.
* gas/arm/ldconst.s: Add test cases for symbol literal.
* gas/arm/ldconst.d: Likewise.
* gas/arm/vldconst.s: Add test cases for vldr.
* gas/arm/thumb2_vpool.s: Likewise.
* gas/arm/vldconst.d: New pattern for little-endian.
* gas/arm/thumb2_vpool.d: Likewise.
* gas/arm/vldconst_be.d: New pattern for big-endian.
* gas/arm/thumb2_vpool_be.d: Likewise.
