I guess something wrong with hard register preferencing for multi-register
pseudos in ira-color.c::ira_assign.  I believe it works fine for one-register
pseudos.  I'll look at this.  Thanks for reporting.

By the way, your patch is wrong.  There should be TARGET_64BIT in define_split
instead of !TARGET_64BIT.
