Add sanity check for Vector API class before trying to intrinsify

Last commit accidentally removed the check that recovered type must
be known Vector API class. This is because mapping information like
type and size must be recovered and this is only possible with a
manual mapping at this time. This check should not be needed when
Vector API intrinsification support is complete.
