Jason Molenda 1d42c7bc32 Switch nearly all of the use of the UnwindPlan::Row's to go through ... a shared pointer to ease some memory management issues with a patch I'm working on. The main complication with using SPs for these objects is that most methods that build up an UnwindPlan will construct a Row to a given instruction point in a function, then add additional regsaves in the next instruction point to that row and push it again. A little care is needed to not mutate the previous instruction point's Row once these are switched to being held behing shared pointers. llvm-svn: 160214		2012-07-14 04:52:53 +00:00
