Why would the auto-vectorizer use the builtins directly? I and many
others think that the auto-vectorizer should be more target generic
The vectorizer needs to be able to make accurate cost estimates for
a specific target to decide what loop optimizations will be beneficial,
so it needs to know exactly what operations are available for each
vector type. The vectorizer algorithms can still be target-independent.
