x86emul: correct EVEX decoding

While these are latent issues only for now, correct them right away:
- unnamed (in the SDM) EVEX bits need to be set/clear respectively
- EVEX.V' (called RX in our code) needs to uniformly be 1 in non-64-bit
  modes,
- EXEX.R' (called R in our code) is uniformly being ignored in
  non-64-bit modes.
