3fabbe0b7d458d6380f4b3246b8b32400f6bd1d9 target/i386: move prefetch and multi-byte UD/NOP to new decoder
These are trivial to add, and moving them to the new decoder fixes some
corner cases: raising #UD instead of an instruction fetch page fault for
the undefined opcodes, and incorrectly rejecting 0F 18 prefetches with
register operands (which are treated as reserved NOPs).
