Missing function arguments in regression tests

After all registers are localized as proposed in #652, some regression tests fail. Those that fail due to missing/unrecognized function arguments will be noted here.

This is different to #653, because cases in this issue do not require tracing beyond previous function calls, and should/could be detected using the current function argument detection algorithm without any major enhancements - at least it looks like it to me after a short investigation, maybe there are other complex problems at play here. If so, investigate more and open more specialized issues.

All cases here are however pre-existing (regarding #652) issues, that were only made visible by this change - they are not caused by the localization itself.
