Added support for setting number of iterations from command line for staggered_dslash_test.
Added support for naive staggered operator (QudaDiracType::QUDA_STAGGERED_DIRAC and QudaDslashType::QUDA_STAGGERED_DSLASH).  Only supports single GPU and no reconstruction support.
Added support for naive staggered fermions in staggered_dslash_test.cpp.
Correct flop count for DiracStaggered
Added naive staggered support to staggered_invert_test and small cleanup to tests for naive staggered.
