x86: %riz, %rip, and %eip don't require REX
While these can't be used as register operands, they can be used for
memory operand addressing. Such uses do not prevent conversion: The
RegRex64 checks in check_Rex_required() for base and index registers
were simply wrong. They specifically also aren't needed for byte
registers, as those won't pass i386_index_check() anyway.
