This sinks the two stores in this example into a single store in cond_next. In this
case, it allows elimination of the load as well:
store double 0.000000e+00, double* @s.3060
%tmp3 = fcmp ogt double %tmp1, 5.000000e-01 ; <i1> [#uses=1]
br i1 %tmp3, label %cond_true, label %cond_next
cond_true: ; preds = %entry
store double 1.000000e+00, double* @s.3060
br label %cond_next
cond_next: ; preds = %entry, %cond_true
%tmp6 = load double* @s.3060 ; <double> [#uses=1]
