target/i386: Introduce REX_PREFIX
The existing flag, x86_64_hregs, does not accurately describe its setting. It is true if and only if a REX prefix has been seen. Yes, that affects the "h" regs, but that's secondary. Add PREFIX_REX and include this bit in s->prefix. Add REX_PREFIX so that the check folds away when x86_64 is compiled out. Fold away the reg >= 8 check, because bit 3 of the register number comes from the REX prefix in the first place.
