Craig Topper aab90384a3 [Attributes] Add a method to check if an Attribute has AttrKind None. Use instead of hasAttribute(Attribute::None) ...

There's a special case in hasAttribute for None when pImpl is null. If pImpl is not null we dispatch to pImpl->hasAttribute which will always return false for Attribute::None.

So if we just want to check for None its sufficient to just check that pImpl is null. Which can even be done inline.

This patch adds a helper for that case which I hope will speed up our getSubtargetImpl implementations.
