LSE improvement: better singleton array optimization
Rationale: In a recent LSA/LSE refactoring, we removed the "exceptional" situation on mismatched arrays from the load-elimination branch for merged values. As a direct result, we can relax the condition on removing stores for singleton arrays into return blocks a bit, as done in this CL (and shown with some tests). Test: test-art-host,target Bug: b/77906240 Change-Id: I32c89057168730f82d1d7c41155a9ff71b126204
