Fix a compact unwind encoding logic bug which would try to encode more callee saved registers than it should, leading to early bail out in the encoding logic and abusive use of DWARF frame mode unnecessarily. Also remove no-compact-unwind.ll which was testing the wrong thing based on this bug and move it to valid 'compact unwind' tests. Added other few more tests too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223676 91177308-0d34-0410-b5e6-96231b3b80d8
