I want to have a special kind for the vectorizer because this will
allow us to communicate warnings to the user that a #pragma vectrorise
enable could not be fulfilled because the target has no vectors, or
there is a memory conflict. This is important to go beyond the debug
level into warning level.

I may not have understood Hal's proposal too well, then. Ignore my
comments... ;)
