On a 2.5Ghz Core2Duo, compiling the test with revision 192891 (2012-10-28)
takes a small fraction of a second, while with revision 193270 (2012-11-06)
it takes ~25s.

However this patch makes gfortran.dg/reassoc_4.f to fail

FAIL: gfortran.dg/reassoc_4.f  -O   scan-tree-dump-times reassoc1 "[0-9] \\\\* 
" 22

After it 22 should be replaced with 16 (thresshold 
max-completely-peeled-insns=138
gives 16, =139 gives 22).
