This upgrade suffers from the problems of the old EH scheme - i.e., that the calls to llvm.eh.exception() and llvm.eh.selector() can wander off and get lost. It makes a valiant effort to reclaim these little lost lambs. This is a first draft, so it hasn't yet been hooked up to the parser. llvm-svn: 138602
