external/firebird: clang-cl needs -march=x86-64-v2 now
...to avoid
> C:/lo/core/workdir/UnpackedTarball/firebird/src/common/CRC32C.cpp(41,10):
error: always_inline function '_mm_crc32_u8' requires target feature 'sse4.2',
but would be inlined into function 'CRC32C' that is compiled without support
for 'sse4.2'
> return _mm_crc32_u8(hash_value, *value);
> ^
etc.
With <https://github.com/FirebirdSQL/firebird/commit/
52d9a05a0f3d811a9de7f15956ee9286d5711648> "Backport from master", that code
appeared on the B3_0_Release branch only after R3_0_1, so was not present
in our
Firebird-3.0.0.32483-0.tar.bz2 before
86744f03992213af162df6954313c9f9e44e3a0a
"firebird: update to 3.0.7".
This is apparently about the SSE4.2 CRC32 instruction. Not sure how this
works
in the MSVC build, whether it implicitly generates code targeting SSE4.2
(<https://docs.microsoft.com/en-us/cpp/build/reference/arch-x64?view=msvc-160>
"/arch (x64)" does not mention any switch to explicitly enable it), or
whether
its _mm_crc32_u* intrinsics would be smart enough to generate code that also
works when SSE4.2 is not available at runtime.
