[Bug middle-end/32269] New: [4.3 Regression] 403.gcc miscompiled

[rguenth at gcc dot gnu dot org]

SPEC2006 403.gcc is miscompiled so we ICE building scilab.i:

scilab.i:12953: Internal compiler error in remove_useless_values, at
cselib.c:394

flags used for building 403.gcc are -O3 -funroll-loops -fpeel-loops
-ftree-vectorize.  (base with -O2 still works ok)

The change happened between r125530 (last working rev) and r125567 (first
failing rev).
