[Bug tree-optimization/21596] [4.0/4.1/4.2 Regression] extra temporaries when using global register variables

Actually we get:
        subl    $4, %edi
        subl    $12, %esp
        xorl    %eax, %eax
        cmpl    $0, -4(%edi)
        setle   %al
        addl    $12, %esp

So this is fixed for the trunk.
