default PcodeUseropDefinition<byte[]> getUseropDefinition(String name) {
		return thread().getUseropLibrary().getUserops().get(name);
	}
Retrieve a userop definition from the bound thread.

<p>
This is invoked by generated constructors to retain a userop reference for later invocation.
Note that it is the userop as defined by the user or emulator, not any wrapper used during
decode or translation. Depending on the invocation strategy, this reference may be saved and
later used with {@link #invokeUserop(PcodeUseropDefinition, Varnode, Varnode[])}, or its
method and instance may be extracted and saved for Direct invocation later.

@param name the name of the userop
@return the userop or {@code null}
