[GlobalISel] Add missing pass dependencies for IRTranslator

The IRTranslator depends on the branch probability info pass when the
optimization level is different than None and it depends all the time on
the StackProtector pass.

We have to explicitly call out pass dependencies otherwise the pass manager
may not be able to schedule the IRTranslator.

Before this patch, we were lucky because previous passes depend on the branch
probability info pass (like the Global Variable Optimization) and the stack
protector pass is initialized in initializeCodeGen.
However, if the target has a custom pipeline without any passes like Global
Variable Optimization, the pipeline creation will fail, at least because of
the branch probability info pass dependency (it is unlikely that
initializeCodeGen is not called).

This patch adds the missing dependencies to the IRTranslator.
