Two changes:
1. If an incoming argument is dead, don't load it from the stack 2. Do not code gen noop copies at all (ie, cast int -> uint), not even to a move. This should reduce register pressure for allocators that are unable to coallesce away these copies in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12835 91177308-0d34-0410-b5e6-96231b3b80d8
