  [TwoAddressInstructionPass] Relax assert in statepoint processing.

D124631 added special processing for STATEPOINT instructions.
It appears that assertion added there is too strong. We can get two
tied operands with the same register tied to different defs. If we
hit such case, do not process it in statepoint-specific code and
delegate it to common case.
