How to tell IRA to use misaligned DImode load?

[H.J. Lu]

Hi,

On my target, SCmode is 4 byte aligned.  But to load it into
a register, it must be 8byte aligned.  I can handle misaligned
load in backend.  But IRA generates misaligned load directly
when SCmode is accessed as DImode.  How can I tell IRA to use
misaligned load for DImode?

Thanks.
