[PR,tdep/20928] Decode properly flags of %ccr register on sparc64

commit 45deb2dd37000fc4f51529e0fc5d206cbbeba983
Author: Ivo Raisr <ivo.raisr@oracle.com>
Date:   Tue Mar 7 10:21:02 2017 +0100

    Decode properly flags of %ccr register on sparc64.
    While at it, decode also properly one-bit flags for %fsr (accrued
    and current exception flags were mixed up).
    
    Tested successfully on sparc64-linux-gnu.
