◆ add() [5/9]

void AliasSetTracker::add ( const MemoryLocation & Loc )

These methods are used to add different types of instructions to the alias sets.

Adding a new instruction can result in one of three actions happening:

If the instruction doesn't alias any other sets, create a new set.
If the instruction aliases exactly one set, add it to the set
If the instruction aliases multiple sets, merge the sets, and add the instruction to the result.
