State-Changed-Why:
    This PR has now been duplicated as c/6957 which has more
    detailed information, so I'm closing this one.  (It's a
    pity that no followup has been made to the request for
    more detailed information, or GCC 3.1 might have had this
    fixed in time.)

>Description:
When compiling Mesa 4.0.2, compiling stops with report:
image.c: In function `_mesa_unpack_chan_color_span':
image.c:2874: could not find a spill register
(insn 1618 1616 1619 (set (subreg:SF (reg:QI 277) 0)
        (plus:SF (reg:SF 8 st(0) [278])
            (reg:SF 9 st(1) [282]))) 525 {*fop_sf_comm_nosse} (insn_list 1609 (nil))
    (expr_list:REG_DEAD (reg:SF 8 st(0) [278])
        (nil)))
image.c:2874: Internal compiler error in failed_reload, at reload1.c:5040

>How-To-Repeat:
Compiling Mesa 4.0.2, configured for i686-pc-linux-gnu, without glide, svga and ggi, and with sse instructions turned both on and off.

Compilation finishes finely with 3.0.4.
