[X86] Remove the single AdSize indicator and replace it with separate AdSize16/32/64 flags.
This removes a hardcoded list of instructions in the CodeEmitter. Eventually I intend to remove the predicates on the affected instructions since in any given mode two of them are valid if we supported addr32/addr16 prefixes in the assembler.
