1. Fix AVX detection …

   The old/faulty code would try to use AVX/AVX2 if either the SSE bit or
   the AVX bit were set in XCR0, but did not check if both bits were set.
   
   In most cases, this still worked, but on some machines, enabling linux
   kernel mitigations for the "gather data sampling" vulnerability results
   in only the SSE bit but not the AVX bit being set, thus resulting in an
   illegal instruction and crashing the application.
   
   Fix this by checking that both bits are set.
   
   Fixes: 4bbb590 ("Proper check of CPU's AVX2 feature support (with MSVC support)")
