When using MachineInstr operand indices on SDNodes, the number

of MachineInstr def operands must be subtracted out. This bug
was uncovered by the recent x86 EFLAGS optimization. Before

things like CMP32rm, where NumDefs is zero.

Do not abort on failure to resolve an external symbol when using dlsym stubs,
