public JitOp getJitOp(PcodeOp op) {

Get the use-def op node for the given p-code op

<p>
NOTE: When used in testing, if the passage is manufactured from a {@link PcodeProgram}, the
decoder will re-write the p-code ops as {@link DecodedPcodeOp}s. Be sure to pass an op to
this method that comes from the resulting {@link JitPassage}, not the original program, or
else this method will certainly return {@code null}.

@param op the p-code op from the source passage
@return the node from the use-def graph, if present, or {@code null}
