x86: ignore high register select bit(s) in 32- and 16-bit modes
While commits 9889cbb14e ("Check invalid mask registers") and abfcb414b9 ("X86: Ignore REX_B bit for 32-bit XOP instructions") went a bit into the right direction, this wasn't quite enough: - VEX.vvvv has its high bit ignored - EVEX.vvvv has its high bit ignored together with EVEX.v' - the high bits of {,E}VEX.vvvv should not be prematurely zapped, to allow proper checking of them when the fields has to hold al ones - when the high bits of an immediate specify a register, bit 7 is ignored
