Jan Beulich 5cec8d231f x86: AVX instruction emulation fixes ...

- we used the C4/C5 (first prefix) byte instead of the apparent ModR/M
  one as the second prefix byte
- early decoding normalized vex.reg, thus corrupting it for the main
  consumer (copy_REX_VEX()), resulting in #UD on the two-operand
  instructions we emulate

Also add respective test cases to the testing utility plus
- fix get_fpu() (the fall-through order was inverted)
- add cpu_has_avx2, even if it's currently unused (as in the new test
  cases I decided to refrain from using AVX2 instructions in order to
  be able to actually run all the tests on the hardware I have)
- slightly tweak cpu_has_avx to more consistently express the outputs
  we don't care about (sinking them all into the same variable)
