Don't use _pext_u64() directly This intrinsic to call BMI2 PEXT instruction is defined in immintrin.h. This header should be included only when USE_PEXT is defined, otherwise we define _pext_u64 as 0 forcing a nop. But under some mingw platforms, even if we don't include the header, immintrin.h gets included anyhow through an include chain that starts with STL <algorithm> header. So we end up both defining _pext_u64 function and at the same time defining _pext_u64 as 0 leading to a compile error. The correct solution is of not using _pext_u64 directly. This patch fixes a compile error with some mingw64 package when compiling with x86-64. No functional change.
