A duplicate insn is one that is appears to be executed twice in a row. This is currently possible due to -icount and cpu_io_recompile() causing a re-translation of a block. On it's own this won't trigger any tests though. The heuristics that the plugin use can't deal with the x86 rep instruction which (validly) will look like executing the same instruction several times. To avoid problems later we tweak the rules for x86 to run the "inline" version of the plugin. This also has the advantage of increasing coverage of the plugin code (see bugfix in previous commit).
