    * config/arm/neon.md (widen_<us>sum<mode>): New patterns where
    mode is VQI to improve mixed mode vectorization.
    * config/arm/neon.md (vec_sel_widen_ssum_lo<VQI:mode><VW:mode>3): New
    define_insn to match low half of signed vaddw.
    * config/arm/neon.md (vec_sel_widen_ssum_hi<VQI:mode><VW:mode>3): New
    define_insn to match high half of signed vaddw.
    * config/arm/neon.md (vec_sel_widen_usum_lo<VQI:mode><VW:mode>3): New
    define_insn to match low half of unsigned vaddw.
    * config/arm/neon.md (vec_sel_widen_usum_hi<VQI:mode><VW:mode>3): New
    define_insn to match high half of unsigned vaddw.
    * config/arm/arm.c (arm_simd_vect_par_cnst_half): New function.
    (arm_simd_check_vect_par_cnst_half_p): Likewise.
    * config/arm/arm-protos.h (arm_simd_vect_par_cnst_half): Prototype
    for new function.
    (arm_simd_check_vect_par_cnst_half_p): Likewise.
    * config/arm/predicates.md (vect_par_constant_high): Support
    big endian and simplify by calling
    arm_simd_check_vect_par_cnst_half
    (vect_par_constant_low): Likewise.
    * testsuite/gcc.target/arm/neon-vaddws16.c: New test.
    * testsuite/gcc.target/arm/neon-vaddws32.c: New test.
    * testsuite/gcc.target/arm/neon-vaddwu16.c: New test.
    * testsuite/gcc.target/arm/neon-vaddwu32.c: New test.
    * testsuite/gcc.target/arm/neon-vaddwu8.c: New test.
    * testsuite/lib/target-supports.exp
      (check_effective_target_vect_widen_sum_hi_to_si_pattern): Indicate
      that arm neon support vector widen sum of HImode TO SImode.
