avoid a bunch of checks in the likely display path
rep_any will get speculated `false` quite quickly, whereas checking if
the opcode is a string instruction will be costly no matter what. in the
rare case rep_any is true, i don't care how costly displaying the
instruction is - string instructions are relatively rare, and rep movs
is typically not more than one instance when it shows up.
