Migrate IR passes from RemillTranslationContext::FinalizeModule()

[surovic]

To facilitate usage of modules that were lifted by other remill-based tools (most notably McSema), IR passes such as RemillArgumentRecovery and RemillStackRecovery need to be run outside of RemillTranslationContext::FinalizeModule(). Ideally put into RunPassPipeline() or a related function in main.cpp. This will allow the passes to be run independently of lifting,
