Using basic constant propagation (only integer constants, no arithmetic calculations), rewrite conditional jump instructions with constant arguments. This covers problem description in KT-17007. Note that it also works transparently with inline functions. Partial evaluation is required to cover more "advanced" cases. As a side effect, this also covers KT-3098: rewrite IF_ICMP<cmp_op>(x, 0) to IF<cmp0_op>(x).
