Chris Lattner c0f6402a94 Fix the Convert to scalar to not insert dead loads in the store case. The load is needed when we have a small store into a large alloca (at which point we get a load/insert/store sequence), but when you do a full-sized store, this load ends up being dead. This dead load is bad in really large nasty testcases where the load ends up causing mem2reg to insert large chains of dependent phi nodes which only ADCE can delete. Instead of doing this, just don't insert the dead load. This fixes rdar://6864035 llvm-svn: 91917		2009-12-22 19:33:28 +00:00
