commit r12-2869-g95e1eca43d106d821720744ac6ff1f5df41a1e78
Author: liuhongt <hongtao.liu@intel.com>

Combine avx_vec_concatv16si and avx512f_zero_extendv16hiv16si2_1 to
avx512f_zero_extendv16hiv16si2_2.
Add define_insn_and_split to combine avx_vec_concatv16si/2 and
avx512f_zero_extendv16hiv16si2_1 since the latter already zero_extend
the upper bits, similar for other patterns which are related to
pmovzx{bw,wd,dq}.
It will do optimization like
- vmovdqa %ymm0, %ymm0 # 7 [c=4 l=6] avx_vec_concatv16si/2
vpmovzxwd %ymm0, %zmm0 # 22 [c=4 l=6]
avx512f_zero_extendv16hiv16si2
ret # 25 [c=0 l=1] simple_return_internal
