* cipher/sha1-avx-amd64.S: Enable when
HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS defined.
(ELF): New macro to mask lines with ELF specific commands.
* cipher/sha1-avx-bmi2-amd64.S: Ditto.
* cipher/sha1-ssse3-amd64.S: Ditto.
* cipher/sha1.c (USE_SSSE3, USE_AVX, USE_BMI2): Enable
when HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS defined.
[USE_SSSE3 || USE_AVX || USE_BMI2] (ASM_FUNC_ABI)
(ASM_EXTRA_STACK): New.
(_gcry_sha1_transform_amd64_ssse3, _gcry_sha1_transform_amd64_avx)
(_gcry_sha1_transform_amd64_avx_bmi2): Add ASM_FUNC_ABI to
prototypes.
(transform): Add ASM_EXTRA_STACK to stack burn value.

Patch gives small improvement for large buffer processing, on Intel i5-4570
speed goes from 4.80 c/B to 4.61 c/B.

* cipher/sha1-ssse3-amd64.S: Remove check for
HAVE_INTEL_SYNTAX_PLATFORM_AS.
* cipher/sha1.c [USE_SSSE3]: Ditto.
--
SHA-1 SSSE3 implementation uses AT&T syntax so check for
HAVE_INTEL_SYNTAX_PLATFORM_AS is unnecessary.

* cipher/sha1-ssse3-amd64.c: Remove.
* cipher/sha1-ssse3-amd64.S: New.
--
Mixed C&asm implementation appears to trigger GCC bugs easily. Therefore
convert SSSE3 implementation to pure assembly for safety.
Benchmark also show smallish speed improvement.
