[PATCH] D4583: don't transform splats of vector FP (PR20358)

[Arnold Schwaighofer via llvm-commits]

This might penalize programs that don't traffic in denormals (most programs as I understand it). Did you measure the performance impact?

Did the bug report originate from a real program where this is an issue?

Though, I agree that putting a denormal on the execution path where it was not before seems like  bad form.
