Fix in codegen for inlined sequence nodes.
For inlined sequence nodes, generate nested ifs rather than sequential code which
does not work when inlined. The reason is that #codeReturn: in inline generates
instvar assignment, not method return, so in sequential code the next child of a sequence
will be probed even if previous failed. If that happends, the whole sequence fail and therefore
we must generate nested ifs to correctly handle this w.r.t. inlining.
