Add SM3 x86-64 AVX/BMI2 assembly implementation
* cipher/Makefile.am: Add 'sm3-avx-bmi2-amd64.S'.
* cipher/sm3-avx-bmi2-amd64.S: New.
* cipher/sm3.c (USE_AVX_BMI2, ASM_FUNC_ABI, ASM_EXTRA_STACK): New.
(SM3_CONTEXT): Define 'h' as array instead of separate fields 'h1',
'h2', etc.
[USE_AVX_BMI2] (_gcry_sm3_transform_amd64_avx_bmi2)
(do_sm3_transform_amd64_avx_bmi2): New.
(sm3_init): Select AVX/BMI2 transform function if support by HW; Update
to use 'hd->h' as array.
(transform_blk, sm3_final): Update to use 'hd->h' as array.
* configure.ac: Add 'sm3-avx-bmi2-amd64.lo'.
