iss #1219 #1223 #1224 reference ignored in name from address (#1222) 
* #1219 added code to check reference mod bit in ClassicCheckPointAgent::getCompositeSubReference, use reference width instead of size.

* #1219 refactor getCompositeSubReference for readability

* #1219 and #1223 add reference width to mod bits in ICG

* check for mod bits in TRICK_STRUCTURED section, refactor function

* #1219 adding MM_ref_name_from_address tests

* #1224 fix logic for offset into arrayed struct

closes #1219 closes #1223 closes #1224
