Change typeIncompatible to return an AttrBuilder instead of new-ing an AttributeSet.

Browse Source 
This makes use of the new API which can remove attributes from a set given a builder.

This is much faster than creating a temporary set and reduces llc time by about 0.3% which was all spent creating temporary attributes sets on the context.
