Please find attached a patch which fixes PR tdep/20928.

Register %ccr on sparcv9 (called sparc64 in gdb's speak) contains 
several flags
{icc,xcc}.{cnvz}. They should be properly decoded such as %fprs, %pstate 
and %fsr is done currently.

While at it, decode also properly one-bit flags of %fsr - accrued and 
current
exception flags were mixed up.

Regression test suite was run successfully with gdb 7.11 on Solaris/sparcv9.
gdb's commands 'info registers' and 'info all-registers' show %ccr with 
correctly decoded flags.
