Floating Pt. Optimize on PA

[Mark Klein]

The attached code at -O2 fails with egcs-1.1b and egcs-1.1.1. It
works correctly in gcc 2.8.1.

Analysis:

        fldds 0(0,%r19),%fr8
        ldw -120(0,%r30),%r20
        ldo -120(%r30),%r21
        fstds %fr8,0(0,%r21)
        addil LR'L$C0002-$global$,%r27
        stw %r20,16(0,%r4)
        copy %r1,%r22
        ldw 4(0,%r21),%r24
        copy %r20,%r25
        stw %r24,20(0,%r4)
        .CALL ARGW0=GR,ARGW1=GR,ARGW2=GR
        bl printf,%r2
        ldo RR'L$C0002-$global$(%r22),%r26

The second instruction (ldw -120(0,%r30),%r20) is attempting to
load the high order 32 bits of the floating point value into a
general register before the floating point value has been saved
into the frame.
