Improve the return slot optimization to be both more aggressive (not limited to sret parameters), and safer (when the passed pointer might be invalid). Thanks to Duncan and Chris for the idea behind this, and extra thanks to Duncan for helping me work out the trap-safety. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48280 91177308-0d34-0410-b5e6-96231b3b80d8
