Conversely, Analysis-implementations do NOT need to initialize the AnalysisGroup.  It will only matter when
someone tries to require that AG, in which case it is the requester's responsibility to initialize it.

explicit disassembler testcase for the instruction.

explicitness is good, especially with the integrated assembler coming in
the future.

getExpandedRegion() enables us to create non canonical regions. Those regions
can be used to define the largerst region, that fullfills a certain property.
