Feed semantics to the genExecInstruction calls
...
These lists come from semmc and contain the bytestrings of the semantics files
for each opcode.
NOTE: The lists are currently empty (presumably due to bugs), but the logic for
moving data around and setting up a SimpleBuilder instance is at least right.
