x86: relax redundant REX prefix check
All REX bits can be specified via individual prefixes. Redundancy should only be reported on a per-bit basis. Note that I originally had further checks added to the test case, checking the effect also on PDEP. I had to strip those, because my patch to correctly handle those (https://sourceware.org/ml/binutils/2017-02/msg00280.html) was rejected. I continue to think that there should not be any new prefix introduced to handle the VEX case - whether the encoding of an insn requires VEX et al should not be of immediate interest to the programmer.
