Peter Collingbourne 43f785d798 CGP: Clear data structures at the end of a loop iteration instead of the beginning.
Clearing LargeOffsetGEPMap at the end fixes a bug where if a large
offset GEP is in a dead basic block, we fail an assertion when trying
to delete the block due to the asserting VH in LargeOffsetGEPMap.
