[PATCH] x86: AVX instruction emulation fixes
...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 (si...
