ART: Fix DeadPhiHandling creating >2 equivalents
Run test 531 failed a DCHECK because the DeadPhiHandling algorithm
would generate three phis of the same type:
(0) loop phi [#0, ref] with equivalents void & object
(1) type object equivalent by its first input => int & int
(2) request object equivalent by a user => int & int & object
(3) type second => int & object & object (dead)
(4) type first => object & object & object
This patch fixes the issue by skipping (1) when the phi already has
a type, thus not creating the third equivalent for the phi's user.
