Add new integer comparison primitives Iop_CasCmp{EQ,NE}{8,16,32,64},
which are semantically identical to Iop_Cmp{EQ,NE}{8,16,32,64}. Use
these new primitives instead of the normal ones, in the tests
following IR-level compare-and-swap operations, which establish
whether or not the CAS succeeded. This is all for Memcheck's benefit,
as it really needs to be able to identify which comparisons are
CAS-success tests and which aren't. This is all described in great
detail in memcheck/mc_translate.c in the comment
"COMMENT_ON_CasCmpEQ".
