ce1e8efc43 Okay, yes there *is* a getKeyLength method on ValueName. And, it should be 
used because we *do* want to allow nulls in names.

22114c319a Before assuming that the original code didn't work for Athlon64, the person who 
replaced it with a FIXME should have determined what did work.  Then he would have
realized that the code was in fact correct, and would have avoided breaking it.

31755a024d Extend store merging to support the 'if/then' version in addition to if/then/else. 
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]

This implements Transforms/InstCombine/store-merge.ll:test2
