New Revision: 210879

URL: http://llvm.org/viewvc/llvm-project?rev=210879&view=rev
Log:
Remove unused variables

Address the 'variable set but not used' warning from GCC.  In some cases a few
additional calls were removed where there should be no visible side effects of
the calls (i.e. should not effect any cached state).
