commit 44fbc9c6e02ca5b8f98f25b514ed7588e7ba733d

    Take insn scratch RA requirements into account in IRA.

      The patch changes insn scratches which require registers for all
    insn alternatives (in other words w/o X constraint in scratch
    constraint string).  This is done before IRA staring its work.  LRA
    still continue to change the rest scratches (with X constraint and in
    insn created during IRA) into pseudos.  As before the patch at the end
    of LRA work, spilled scratch pseudos (for which X constraint was
    chosen) changed into scratches back.=
