Merge #13393: Enable double-SHA256-for-64-byte code on 32-bit x86
57ba401abcfe564a2c4d259e0f758401ed74616d Enable double-SHA256-for-64-byte code on 32-bit x86 (Pieter Wuille)
Pull request description:
The SSE4 and AVX2 double-SHA256-for-64-byte input code from #13191 compiles fine on 32-bit x86 systems, but the autodetection logic in sha256.cpp doesn't enable it. Fix this.
Note that these instruction sets are only available on CPUs that support 64-bit mode as well, so it is only beneficial in the (perhaps unlikely) scenario where a 64-bit CPU is running a 32-bit Bitcoin Core binary.
