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).
