Chris Lattner aadadb3973 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
