With this change, allocation instructions can now be direct inputs to other allocation instructions, so the redundancy eliminator is extended to handle this possibility. Methods for working with instruction input-related slots are added to subclasses of AllocationInstr, so that the redundancy eliminator can be written more generically in places, instead of needing to add cases for new allocation instructions and/or instruction inputs. Code size different in Flutter gallery (release-sizeopt): * ARM7: Total -0.30%, instructions -0.41% * ARM8: Total -0.31%, instructions -0.47% TEST=Current test suite.
