mesa/dlist: don't cache state which may not be replayed on CallList
Statechanges which occur before the first End in a display list may
not be replayed when the list is called, in particular if it is called
from within a begin/end pair.
Recognize vulnerable statechanges and do not use them to fill in the
state cache.
