If this becomes a performance bottleneck, we could precompute this value when
they are set, and perform a single check, skipping the Word32Or.

This is what we do when calling a function: we need to check whether we are
stepping, and whether we need to perform a side-effect check. Both are
debugger-related, and we have Debug::hook_on_function_call_ field that we expose
via external reference to generated code.

Done.
