x86/APX: correct disassembly for EVEX.B4

EVEX.B4 is used only for GPR (or addressing of memory) operands. SIMD
registers encoded via ModR/M.rm (when ModR/M.mod == 3) have their top
bit in EVEX.X3. Supposedly (doc version 004) EVEX.B4 is ignored when
unused, hence also don't flag such encodings as invalid.
