[PATCH] D69982: PPC: Prepare tests for switch of default denormal-fp-math

Well, it seems that it is still too early to review this change. One comments: I see that, we have the code sequence change if switch to ieee. sqrt_afn_ieee is slower than sqrt_afn.  As you are trying to set it as ieee for target that didn't explicit set the denormal-fp-math, which means that, this will affect PowerPC. Could we have the Frontend set the denormal-fp-math for PowerPC as non-ieee, so that, you don't need this patch any more ?
