Currently _Complex is classified as SSE_REG_CLASS, and need two 2 hardreg to
handle it. We may need to handle things like TARGET_HARD_REGNO_MODE_OK in
backend. So that ira can work suitable for our complex operation.

Can IRA allocate registers for SCmode and DCmode?

This is due to nonexistent SCmode patterns. I guess that movsc pattern is
needed here.
