[Bug fortran/35418] [4.4 Regression]: Revision 132592 miscompiles 172.mgrid

Note the COND_EXRPs will be lowered to control-flow while the MAX_EXPRs will
retain a single BB.  Still, on i686 the exactly same inner loop IL is created.

And btw I don't see mgrid miscomparing on our tester that runs with -O3 vs.
-O3 -funroll-loops -fpeel-loops -ffast-math.  But indeed the other tester
with -O2 -ffast-math vs. -O2 -ffast-math with FDO miscompares since Feb. 25
(not so with 32bit or on IA64 though).
