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
