Simplify RegScavenger::forward a bit more. Verify that early clobber registers and their aliases are not used. All changes to RegsAvailable are now done as a transaction so the order of operands makes no difference. The included test case is from PR4686. It has behaviour that was dependent on the order of operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78465 91177308-0d34-0410-b5e6-96231b3b80d8
