default PcodeUseropDefinition<T> getSyscallUserop() {

	}
In case this is not an {@link AnnotatedEmuSyscallUseropLibrary} or
{@link AnnotatedPcodeUseropLibrary}, get the definition of the "syscall" userop for inclusion
in the {@link PcodeUseropLibrary}.

<p>
Implementors may wish to override this to use a pre-constructed definition. That definition
can be easily constructed using {@link SyscallPcodeUseropDefinition}.

@return the syscall userop definition
